The reaction is carried out at temperatures of 0.degree.-100.degree. C., preferably at 100.degree.-140.degree. C. The starting compounds of the formulae II and III and formaldehyde are brought together in approximately equimolar amounts. The formaldehyde can also be employed in excess (about a 1-5-fold excess).
The reaction is usually carried out under normal pressure. However, it is also possible to carry out the reaction under pressure. It is preferably carried out in the presence of diluents. Suitable diluents are hydrocarbons, such as toluene, xylene or benzene, halogenohydrocarbons, such as chloroform, alcohols, such as ethanol or isopropanol, and ethers, such as tert.-butyl methyl ether.
It is also possible to add formaldehyde to the hydroxylamines of the formula II and then to add the alkenes of the formula III to the reaction mixture.
In a particularly preferred procedure, it is also possible to react the hydroxylamines of the formula II in the form of their salts with inorganic or organic acids, in particular HCl, and formaldehyde, preferably as paraformaldehyde in the form of its aqueous formalin solution (3-40%) or with trioxane, and then to add the alkene of the formula III to the reaction solution.
For this, formaldehyde, such as, for example, formalin, is added to the salts of the hydroxylamines of the formula II in suitable diluents and the mixture is then neutralized with strong inorganic or organic bases.
The reaction is carried out at temperatures from -20.degree. to +150.degree. C. under normal pressure.
The starting compounds are brought together in an approximately equimolar ratio. Formaldehyde can also be employed in excess (in about a 1-5-fold excess).
Suitable diluents which may be mentioned are inert organic diluents, such as alcohols, such as methanol, ethanol or isopropanol, hydrocarbons, such as toluene, dimethylformamide, dimethyl sulphoxide, high-boiling ethers, chlorohydrocarbons, such as chloroform, methylene chloride or ethylene chloride.
As strong inorganic bases his alkali and alkaline earth metal hydroxides, such as sodium hydroxide solution or potassium hydroxide solution, alkali and alkaline earth metal carbonates and bicarbonates.
Suitable organic bases which may be mentioned are: Trimethylamine, triethylamine, N-ethyldiisopropylamine, N,N-dimethylaniline, N,N-diethylaniline, N,N,N',N'-tetramethylethylenediamine, N,N,N',N'-tetraethylethylenediamine, lutidine, picoline and pyridine.
The neutralization is carried out at about -20.degree. to +160.degree. C. to a pH value of 6-8.
The alkene of the formula III and a "water-entraining agent" are then added to the reaction mixture.
The reaction mixture is then heated to 110.degree. to 140.degree. C., depending on the boiling point of the water-entraining agent. The alcohol and water are distilled off azeotropically with the aid of the water-entraining agent.
Water-entraining agents which may be mentioned are: Aromatic hydrocarbons, such as, in particular, benzene, toluene or xylene, and halogenated hydrocarbons, such as chloroform or carbon tetrachloride.
After the alcohol has been distilled off and the water has been removed from the reaction mixture with the water-entraining agent, the mixture is allowed to after-react at 110.degree.-140.degree. C. and is then worked up in the customary manner.
As already mentioned, the hydroxylamines of the formula V are new. The process for their preparation can be characterized by the following equation: ##STR45##
The reaction is carried out at -20.degree. to +100.degree. C., preferably at 20.degree. C.
The reaction is carried out under normal pressure.
The starting components are employed in approximately an equimolar ratio.
The reaction is carried out in diluents. Diluents which may be mentioned are: alcohols, such as methanol, ethanol, isopropanol and ethylene glycol. The reaction can also be carried out in aqueous alcohols.
The pH value of the reaction solution is about 1-4. The pH value can be determined by means of a calibrated glass electrode. It is furthermore suitable to add a color indicator, such as bromocresol green or methyl orange, for adjustment of the pH value.
Working up can be effected in a manner which is known per se by acidification of the batch with concentrated acid, such as hydrochloric acid, in order to destroy the cyanoborohydride, and subsequent alkalization, followed by extraction of the N-alylhydroxylamine with organic solvents (compare R. Borch J. Am. Chem. Soc. 93, 2897 (1971).
However, it is particularly advantageous, when the borohydride reduction has ended and the borohydride has been destroyed with concentrated acids, such as hydrochloric acid, to concentrate the batch under a water pump vacuum, and to extract the residue with chloroform, methylene chloride or alcohols, such as ethanol, isopropanol or methanol. The organic solution of the N-alkylhydroxylamine hydrochloride is dried with sodium sulphate or other suitable drying agents and concentrated in a rotary evaporator.
The compounds of the formula V can also be prepared in a manner which is known per se by reduction of the corresponding nitro compounds with hydrogen under catalysis by, for example, palladium-on-charcoal (compare U.S. Pat. No. 3,173,953), or by reduction with zinc dust in glacial acetic acid, with aluminum amalgam or with tin-II chloride (compare Houben-Weyl Methoden der org. Chemie [Methods of organic chemistry] Volume 10/1 page 1153).

The reaction is carried out under normal pressure.
The starting compounds are employed in approximately equivalent proportions, a 1-10-fold excess of formalin being used.
The reaction is carried out in the presence of diluents. Diluents which may be mentioned for the olefination are water and alcohols (methanol, ethanol or isopropanol).
Another process for the preparation of the alkenes of the formula VII can be characterized by the following equation: ##STR47##
Aldehydes of the formula IX which may be mentioned are: 2-Chloro-3,4-methylenedioxy-, 2,4,6-trichloro-5-amino-3,5-dibromo-4-methoxy-, 3-nitro-4-chloro-, 3-phenoxy-3-(4-chlorophenoxy)- and 3-(3-trifluoromethylphenoxy)-benzaldehyde and 3-pyridylaldehyde.
The process is carried out analogously to the process described by R. Broos et al., Synthetic Comm 6(1) 53-57 (1976) and W. S. Emmerson Chem Rev. Volume 45 (1949) page 347.
The reaction is carried out under the usual conditions for a Wittig olefinization. The aldehydes of the formula IX employed are known.
Suitable olefinizing agents according to Wittig are phosphorus ylides, such as Ph.sub.3 P.sup..sym. -CH.sub.3 Cl.sup..crclbar. or Br.sup..crclbar. or I.sup..crclbar..

The reaction is carried out in diluents. Diluents which may be mentioned are: Alcohols, such as methanol or ethanol, hydrocarbons, such as benzene or toluene, ethers, such as diethyl ether, dioxane or tetrahydrofuran, and halogenohydrocarbons, such as methylene chloride.

The active compounds according to the invention can be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with other active compounds, such as insecticides, baits, sterilizing agents, acaricides, nematicides, fungicides, growth-regulating substances or herbicides. The insecticides include, for example, phosphates, carbamates, carboxylates, chlorinated hydrocarbons, phenylureas, substances produced by microorganisms and the like.
The active compounds according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with synergistic agents. Synergistic agents are compounds which increase the action of the active compounds, without it being necessary for the added synergistic agent to be active itself.
The active compound content of the use forms prepared from the commercially available formulations can vary within wide limits. The active compound concentration of the use forms can be from 0.0000001 to 95% by weight of active compound, preferably between 0.0001 and 1% by weight.
The compounds are employed in a customary manner appropriate for the use forms.
When used against hygiene pests and pests of stored products, the active compounds are distinguished by an excellent residual action on wood and clay as well as good stability to alkali on limed substrates.
The active compounds according to the invention are also suitable for combating ectoparasites and endoparasites in the field of verterinary medicine.
The active compounds according to the invention are used in a known manner in the veterinary sector, such as by oral administration, for example in the form of tablets, capsules, drinks and granules, by dermal application, for example in the form of dipping, spraying, pouring on and spotting on, and dusting, and by parenteral administration, for example in the form of an injection.
The active compounds can be used in all areas of animal husbandry as agents for promoting and accelerating growth and for improving the feedstuff utilization of healthy and sick animals.
The activity of the active compounds is largely independent of the species and sex of the animals. The active compounds have proved particularly useful in the rearing and keeping of young animals and fattening animals.
The following stock animals and pets may be mentioned as examples of animals for which the active compounds can be used for promoting and accelerating growth, for improving the feedstuff utilization and for improving the flesh/fat ratio in the carcass: Warm-blooded animals, such as cattle, pigs, horses, sheep, goats, cats, dogs, rabbits, fur-bearing animals, for example mink and chinchilla, poultry, for example chickens, geese, ducks and turkeys, pigeons, parrots and canaries, and cold-blooded animals, such as fish, for example carp, and reptiles, for example snakes.
The amounts of active compounds administered to the animals to achieve the desired effect can be varied substantially because of the advantageous properties of the active compounds. It is preferably about 0.01 to 50, in particular 0.1 to 10 mg/kg of body weight per day. The period of administration can be from a few hours or days up to several years. The appropriate amount of active compound and the appropriate period of administration depend, in particular, on the species, age, sex, state of health and nature of housing and feeding of the animals, and can easily be determined by any expert.
The active compounds are administered to the animals by the usual methods. The nature of the administration depends, in particular, on the species, the behavior and the state of health of the animals. Thus, administration can be effected orally or parenterally, once or several times daily at regular or irregular intervals.
For reasons of expediency, oral administration, in particular in the rhythm of the intake of food and/or drink by the animals, is in most cases to be preferred.
The active compounds can be administered as a pure substance mixture or in formulated form, that is to say mixed with any desired type of non-toxic inert carriers, for example with carriers and in formulations such as are usual in nutritional preparations.
The active compounds, optionally in formulated form, are administered in a suitable form together with pharmaceutically active compounds, mineral salts, trace elements, vitamins, proteins, fats, colorants and/or flavoring agents.
Oral administration together with the feed and/or drinking water is recommended, the active compound being added to the total amount or only to portions of the feed and/or drinking water, as required.
The active compounds can be admixed to the feed and/or drinking water in accordance with customary methods by simple mixing as a pure substance mixture, preferably in finely divided form, or in formulated form as a mixture with edible non-toxic carriers, if appropriate in the form of a premix or a feed concentrate.
The feed and/or drinking water can contain, for example, the active compounds in a weight concentration of about 0.01 to 50 ppm, in particular 0.1 to 10 ppm. The optimum level of the concentration of the active compounds in the feed and/or drinking water depends, in particular, on the amount of feed and/or drinking water taken in by the animals, and can easily be determined by an expert.
The nature of the feed and its composition is irrelevant here. All the customary or specific feed compositions, which preferably contain the usual equilibrium of energy substances and builder substances, including vitamins and minerals, necessary for balanced nutrition, can be used. The feed can be composed, for example, of vegetable substances, for example hay, beet, cereals and cereal by-products, animal substances, for example meat, fats and bonemeal, fish products, vitamins, for example vitamin A, D complex and B complex, proteins, aminoacids, for example DL-methionine, and inorganic substances, for example lime and sodium chloride.
Feed concentrates contain the active compounds, alongside edible substances, for example rye flour, corn flour, soy bean flour or lime, if appropriate with further nutrients and builder substances, as well as proteins, mineral salts and vitamins. They can be prepared by the customary methods of mixing.
Preferably, in premixes and feed concentrates, the active compounds can, if appropriate, also be protected from air, light and/or moisture by suitable agents which coat their surface, for example with non-toxic waxes or gelatin.
The following is an example of the composition of a feed for rearing chicks, which contains an active compound according to the invention: 200 g of wheat, 340 g of corn 361 g of coarse soy bean meal, 60 g of beef tallow, 15 g of dicalcium phosphate, 10 g of calcium carbonate, 4 g of iodized sodium chloride, 7.5 g of a vitamin/mineral mixture and 2.5 g of an active compound premix give, after thorough mixing, 1 kg of feed.
One kg of feed mix contains: 600 international units of Vitamin A, 100 international units of Vitamin D.sub.3, 10 mg of Vitamin E, 1 mg of Vitamin K.sub.3, 3 mg of riboflavin, 2 mg of pyridoxine, 20 mcg of Vitamin B.sub.12, 5 mg of calcium pantothenate, 30 mg of nicotinic acid, 200 mg of choline chloride, 200 mg of MnSO.sub.4 .times.H.sub.2 O, 140 mg of ZnSO.sub.4 .times.7H.sub.2 O, 100 mg of FeSO.sub.4 .times.7H.sub.2 O and 20 mg of CuSO.sub.4 .times.5H.sub.2 O.
The active compound premix contains the active compounds in the desired amount, for example 10 mg, and in addition 1 g of DL-methionine as well as soy bean flour in an amount such that 2.5 g of premix are formed.
The following is an example of the composition of a feed for rearing pigs, which contains an active compound according to the invention: 630 g of shredded cereal feed (composed of 200 g of corn 150 g of shredded barley, 150 g of shredded oats and 130 g of shredded wheat), 80 g of fish meal, 60 g of coarse soy bean meal, 60 g of tapioca meal, 38 g of brewer's yeast, 50 g of a vitamin/mineral mixture for pigs (composition, for example, as for the thick feed), 30 g of linseed cake meal, 30 g of corn gluten feed, 10 g of soy bean oil, 10 g of sugar cane molasses and 2 g of an active compound premix (composition, for example, as for the chick feed) give, after thorough mixing, 1 kg of feed.
The feed mixtures described are intended preferably for rearing and fattening chicks or pigs, but they can also be used, in the same or a similar composition, for rearing and fattening other animals.
Several feeding experiments have been carried out with the active compounds according to the invention.
The following results were obtained:

(b) Treatment of the animals
The animals were acclimated to the new housing conditions for 2 days, the experimental feed generally being administered without the added active compound. On the third day of the experiment, the animals were randomized and the experimental groups then formed so that both the mean values and the deviations in body weights were identical between the groups. A preliminary period of 5 days was followed by a main period of 8 days, during which the feed intake, additional growth and feed utilization were determined.

EXAMPLE
Pyricularia test (rice)/systemic
Solvent: 12.5 parts by weight of acetone
Emulsifier: 0.3 parts by weight of alkylaryl polyglycol ether
To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amounts of solvent, and the concentrate is diluted with water and the stated amount of emulsifier, to the desired concentration.
To test for systemic properties, standard soil in which young rice plants have been grown is watered with 40 ml of the preparation of active compound. 7 days after the treatment, the plants are inoculated with an aqueous spore suspension of Pyricularia oryzae. Thereafter, the plants remain in a greenhouse at a temperature of 25.degree. C. and a relative atmospheric humidity of 100% until they are evaluated.
Evaluation of the disease infestation is carried out 4 days after the inoculation.
In this test, a clearly superior activity compared with the prior art is shown, for example, by the compounds according to the following preparation examples:
EXAMPLE
Pyricularia test (rice)/protective
Solvent: 12.5 parts by weight of acetone
Emulsifier: 0.3 parts by weight of alkylaryl polyglycol ether
To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amounts of solvent, and the concentrate is diluted with water and the stated amount of emulsifier, to the desired concentration.
To test for protective activity, young rice plants are sprayed with the preparation of active compound until dripping wet. After the spray coating has dried on, the plants are inoculated with an aqueous spore suspension of Pyricularia oryzae. The plants are then placed in a greenhouse at 100% relative atmospheric humidity and 25.degree. C.
Evaluation of the disease infestation is carried out 4 days after the inoculation.
In this test, a clealy superior activity compared with the prior art is shown, for example, by the compounds according to the following preparation examples:
EXAMPLE
Laphygma test
Solvent: 3 parts by weight of dimethylformamide
Emulsifier: 1 part by weight of alkylaryl polyglycol ether
To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent and the stated amount of emulsifier, and the concentrate is diluted with water to the desired concentration.
Cabbage leaves (Brassica oleracea) are treated by being dipped into the preparation of active compound of the desired concentration and are infested with caterpillars of the owlet moth (Laphygma frugiperda), as long as the leaves are still moist.
After the specified period of time, the destruction in % is determined. 100% means that all the caterpillars have been killed; 0% means that none of the caterpillars have been killed.
In this test, for example, the following compounds from the preparation examples show a superior activity compared to the prior art:
EXAMPLE
Critical concentration test/soil insects
Test insect: Phorbia antiqua grubs (in the soil)
Solvent: 3 parts by weight of acetone
Emulsifier: 1 part by weight alkylaryl polyglycol ether
To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is added and the concentrate is diluted with water to the desired concentration.
The preparation of active compound is intimately mixed with soil. The concentration of the active compound in the preparation is of practically no importance, only the amount by weight of active compound per unit volume of soil, which is given in ppm (=mg/liter) being decisive. The soil is filled into pots and the pots are left to stand at room temperature.
After 24 hours, the test insects are introduced into the treated soil, and after a further 2 to 7 days the degree of effectiveness of the active compound is determined in % by counting the dead and live test insects. The degree of effectiveness is 100% if all the test insects have been killed and is 0% if just as many test insects are still alive as in the case of the untreated control.
In this test, for example, the following compounds from the preparation examples show a superior action compared to the prior art:
PREPARATION EXAMPLES
General working instructions:
A solution of 0.1 mol of the alkene of the formula III in 250 ml of toluene is heated to 100.degree. C., and an alcoholic aqueous solution obtained by adding 0.11 mol of an aqueous formalin solution (33% strength) to 0.11 mol of hydroxylamine hydrochloride of the formula II, neutralizing with potassium hydroxide solution (1 molar in methanol) and filtering off the potassium chloride, is added.
Methanol initially thereby distils off, and the mixture is then warmed to an external temperature of 140.degree. C. Water thereby distils off azeotropically. The mixture is boiled under reflux for a further 5 hours. It is allowed to cool, solid residues are filtered off and 100 ml of 10% strength hydrochloric acid are added. The mixture is extracted twice with 100 ml of ether and the aqueous residue is rendered alkaline to pH 8-10 with concentrated aqueous sodium hydroxide solution. The mixture is again extracted three times with 100 ml of ether each time. The combined ether extracts are dried over sodium sulphate, the ether is distilled off and the residue is distilled under a high vacuum or reacted with ethanolic hydrochloric acid to give the hydrochloride or reacted with ethanolic oxalic acid to give the oxalate.
The following compounds are obtained by these general instructions.

Preparation of the new hydroxylamines of the formula V.
EXAMPLE a
1,001 g (10 mol) of pinacolone and 822 g (11.8 mol) of hydroxylamine HCl are heated at the reflux temperature with 985 g (12 mol) of sodium acetate in 5 l of ethanol for 12 hours. After the mixture hs been filtered and the filtrate has been concentrated on a rotary evaporator, the residue is extracted by shaking with ether. 954 g of pinacolone oxime of melting point 69.degree. C. (82% yield) are obtained from the ether phase.
115.16 g (1 mol) of pinacolone oxime are dissolved in 500 ml of methanol and the solution is brought to pH 3 with concentrated HCl, against bromocresol green indicator. 62.8 g (1 mol) of NaBH.sub.3 CN are added in small portions, while cooling the batch with ice. During this addition, the pH value is kept at 3 by dropwise addition of concentrated HCl. When the addition has ended, stirring is continued at room temperature for 3 hours.
The batch is brought to pH 1 by careful dropwise addition of concentrated HCl, in order to decompose residual borohydride. The mixture is concentrated on a Rotavapor (together with the precipitate), and the residue is extracted three times with 500 ml of chloroform each time. After drying over Na.sub.2 SO.sub.4, the chloroform is concentrated. The residue crystallises out.
Yield: 124 g (81%), melting point: 115.degree. C. (HCl salt), 51.degree. C. (base).
