Description

The present invention relates to novel benzyl 2-phenyl-1-alk(en)ylcyclopropanecarboxylates of the general formula I ##STR2## where R.sup.1 is halogen or, in each case low molecular weight, alkyl, alkoxy, haloalkyl or haloalkoxy,

R.sup.2 is halogen or, in each case low molecular weight, alkyl or haloalkyl, R.sup.3 and R.sup.4 are halogen or each is an electron in a double bond formed by them together, R.sup.5 is hydrogen or, in each case low molecular weight, alkyl, alkenyl or alkynyl, or cyano, R.sup.6 is halogen or alkyl, R is halogen, n is 1 to 5, m is 1 to 4, p is 0 to 5.

The present invention also relates to pest-control agents which contain the cyclopropanecarboxylic esters I as active ingredients, and to methods for controlling pests with these active ingredients.

It has been disclosed that certains esters of 3-(2-phenylethenyl)-2,2-dimethylcyclopropanecarboxylic acid and alcohols which have a phenoxybenzyl or phenylbenzyl structure have insecticidal properties (cf., for example U.S. Pat. No. 4,536,591, EP 49,977, U.S. Pat. No. 4,332,815, EP 143,152, DE 2,730,515, DE 2,920,947 and EP 03,336).

However, the insecticidal action of these esters is in most cases unsatisfactory under certain conditions, e.g. low application rates or action on certain pests. Accordingly, the object was to prepare substituted benzyl cyclopropanecarboxylates with improved actions.

We have accordingly found that this object is achieved by the benzyl 2-phenyl-1-alk(en)ylcyclopropanecarboxylates I. Pest-control agents containing this active ingredient have a strong insecticidal and acaricidal action.

Unless stated otherwise, the following terms have the following preferred meanings in formula I:

For R.sup.1

Halogen is fluorine, chlorine or bromine;

Alkyl is a straight or branched alkyl of 1 to 6, in particular 1 to 4, carbons, for example, methyl, ethyl, propyl, 1-methylethyl, butyl, 2-butyl, 2-methylpropyl, 1,1-dimethylethyl, 1,1-dimethylpropyl and 2,2-dimethylpropyl;

Haloalkyl is as specified for R.sup.1 ;

For R.sup.3 and R.sup.4

For R.sup.5

Alkyl is a straight or branched chain of 1 to 4 carbons, for example methyl and ethyl.

Alkenyl is a straight or branched chain of 2 to 5 carbons with 1 or 2 double bonds, for example vinyl, 1-propenyl, 2-propenyl, alkenyl and 1,3-butadienyl;

For R.sup.7 halogen is fluorine and chlorine.

n is an integer from 1 to 5, in particular 1 to 3.

p is 0 or an integer from 1 to 5, in particular 0, 1 or 2.

The esters of the general formula I can be obtained in a conventional manner by reacting cyclopropanecarboxylic acids IIa or derivatives thereof, such as chlorides, anhydrides or the like, in which R.sup.8 is a conventional leaving group such as halogen, or is OM where M is an alkali metal or alkaline earth metal such as sodium, potassium, lithium, calcium or magnesium, with benzyl alcohols of the general formula IIIa or derivatives thereof, where R.sup.9 is a conventional leaving group or is OM as defined above. Examples of conventional leaving groups are chlorine, bromine, iodine, O-mesyl, O-tosyl or a fluorinated alkanesulfonyl or arenesulfonyl.

The reaction starting from cyclopropanecarboxylic acid IIa (R.sup.8 =OH) and the benzyl alcohol IIIa (R.sup.9 =OH) is depicted in the following diagram: ##STR3##

The rate of the esterification can be increased in a conventional manner by adding catalysts such as sulfuric acid, hydrogen halide, sulfonic acid or acid ion exchangers, and the esterification equilibrium can be displaced in the desired direction by removing the water or the ester I from the reaction mixture, e.g. by azeotropic distillation or by binding the water to sulfuric or hydrohalic acid.

It is equally possible to react the appropriate acid chlorides with the alcohols of the formula IIIa in the presence of an acid acceptor (cf. Houben-Weyl, Methoden der org. Chemie, Volume VIII, pp. 541 et seq., Georg-Thieme-Verlag, Stuttgart 1952).

Suitable acid-binding agents are the conventional basic agents, in particular aliphatic, aromatic and heterocyclic amines, e.g. triethylamine, dimethylamine, piperidine, dimethylaniline, dimethylbenzylamine, pyridine and 2-picoline.

The reaction can be carried out in a solvent or diluent. Suitable for this are the specified acid acceptors themselves or, for example, the following solvents or diluents or mixtures thereof: aliphatic and aromatic, possibly chlorinated hydrocarbons such as petroleum ether, benzene, toluene, xylene, naphtha, dichloromethane, chloroform, tetrachloromethane, 1,2-dichloroethane and chlorobenzene; ethers such as diethyl and di-n-butyl ether, methyl tert-butyl ether, tetrahydrofuran and dioxane; ketones, for example acetone, methyl ethyl ketone and methyl isopropyl ketone; and nitriles such as acetonitrile and propionitrile.

The starting materials are normally used in the stoichiometric ratio. However, an excess of one or other of them may be advantageous in some cases.

The rate of the reaction above 0.degree. C. is adequate. Since the reaction usually evolves heat, it may be advantageous to provide means for cooling.

In some cases it is worthwhile and advantageous to esterify the compounds of the formula II in situ, especially when R.sup.5 is cyano.

The esters according to the invention can also be prepared by virtually all conventional processes of ester synthesis, for example by reacting appropriate anhydrides with the alcohols of the formula IIIa, by reacting appropriate carboxylic salts with derivatives of the alcohols of the formula IIIa or by transesterification (cf. Houben-Weyl, loc. cit., pp. 508-628).

It is obvious that each of the compounds of the formula I occurs in the form of pure diastereomers, at least one pair of optical antipodes and, in many cases, in the form of multiple diastereomers, and can be used as active ingredients which, depending on the starting materials and the reaction conditions, are in pure form or as mixtures. In some cases their biological action depends on their steric configuration.

Individual stereoisomers of the carboxylic esters of claim 1 can be obtained by employing stereoisomerically pure starting compounds or by fractionating resulting product mixtures into their sterically pure constituents by conventional processes such as preparative TLC, column chromatography, MPLC or HPLC using suitable absorbents such as silica gel or alumina or other commercial absorbents and suitable solvents singly or in a mixture, for example petroleum ether, pentane, hexane, cyclohexane, diethyl ether, methyl tert-butyl ether, diisoproyl ether, toluene, benzene, acetone, methanol, ethanol, ethyl acetate, methylene chloride, chloroform or acetonitrile.

Processes for the preparation of the pyrethroid acids and derivatives thereof which are employed are described, for example, in Wegler, Chemie der Pflanzenschutz- und Schadlingsbekampfungsmittel, Volume 7, pp. 57-66 and 137-172, Springer Verlag, Berlin, Heidelberg, New York 1981; Angew. Chem. Int. Ed. Engl. 20 (1981) 703-722; DE 2,738,150; DE 2,920,947; DE 2,916,357; EP 0,095,047.

Processes for the preparation of the alcohols of the general formula III which are employed, when R.sup.5 =hydrogen and R.sup.9 =OH or bromine, are described, for example, in Pest. Sci. 14, (1983) 560-570.

Compounds of the general formula IV can be prepared from compounds of the general formula III in which R.sup.9 is OH by oxidation by literature methods (Houben-Weyl, Methoden der Org. Chemie, Volume E 3, pp. 275-299). It is likewise possible to prepare the latter from compounds of the general formula III in which R.sup.9 is chlorine or bromine or OSO.sub.2 -p-toluene by literature methods (Houben-Weyl, Methoden der Org. Chemie, Volume E 3, pp. 248-265).

In addition, the benzyl halides of the formula III (R.sup.9 =Cl, Br) can be converted into benzyl alcohols of the formula III (R.sup.9 =OH) by literature methods (Houben-Weyl, Methoden der Org. Chemie, Volume 6/1a/1, pp. 174-223) and subsequently into compounds of the formula IV.

Compounds of the general formula III in which R.sup.5 is alkyl, alkenyl or alkynyl and R.sup.9 is OH may be prepared from compounds of the general formula IV by organometallic reactions in accordance with literature methods (Houben-Weyl, Methoden der Org. Chemie, Vol. 6/1a/2).

Examples of solid carriers are mineral earths such as silicic acid, silica gels, silicates, talc, kaolin, attapulgus clay, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground plastics, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, and ureas, and vegetable products such as grain flours, bark meal, wood meal, and nutshell meal, cellulosic powders, etc.

The formulations generally contain from 0.1 to 95, and preferably 0.5 to 90, % by weight of active ingredient.

The active ingredient concentrations in the finished formulations may vary over a wide range. Generally, they are from 0.0001 to 10, and preferably from 0.01 to 1, %.

MANUFACTURING EXAMPLES

A) trans,Z-3-[2-chloro-2-(4-chlorophenyl)-ethenyl]-2,2-dimethylcyclopropylcarboxylic chloride

174 g (0.22 mol) of anhydrous pyridine is added to a solution of 57 g (0.2 mol) of the appropriate carboxylic acid in 400 ml of anhydrous toluene. At 0.degree. to 5.degree. C., 59.5 g (0.5 mol) of thionyl chloride is dripped in and the whole is stirred for about 24 hours at room temperature. The precipitate is filtered off and the filtrate is evaporated down under reduced pressure. The oil which is obtained is taken up in methyl tert-butyl ether, cooled to 0.degree. C., and the precipitate which forms is filtered off. The filtrate is evaporated down under reduced pressure, and the oil is dissolved in pentane/methyl tert-butyl ether (2/1), cooled to 0.degree. C., and any precipitate which may have formed is filtered off. The filtrate is concentrated. The oil obtained (60 g=98.8% of theory) is sufficiently pure to be used for esterification.

0.87 g (0.011 mol) of anhydrous pyridine is added to 1.98 g (0.01 mol) of 2-methyl-3-phenylbenzyl alcohol in 20 ml of anhydrous toluene. At room temperature, 3.035 g (0.01 mol) of the acyl chloride obtained under A), dissolved in 10 ml of anhydrous toluene, is dripped in. The mixture is stirred for about 18 hours at room temperature. About 100 ml of water is added to the reaction mixture, the organic phase is separated and the aqueous phase is thoroughly extracted several times with methyl tert-butyl ether. The combined organic phases are washed first with about 2N hydrochloric acid, then with water and then with saturated sodium chloride solution, and subsequently dried over sodium sulfate. After removal of the solvent under reduced pressure, 4.2 g of a yellow viscous oil is obtained. Purification by column chromatography on silica gel (230-400 mesh) using a 1:2 mixture of toluene/cyclohexane gives 3.9 g (84% of theory) of a pale yellow oil.

USE EXAMPLES

In the following examples, Compound No. 1.1 was compared with prior art Compounds I and II. ##STR101##

The purity of the substances was >95%. The concentrations at which the investigated compounds exhibit 100% kill are the minimum concentrations. At least two experiments were carried out for each concentration and an average was formed.

The active ingredient was used either as a 0.1% acetonic solution or as a 10% emulsions concentrate obtained by emulsifying the active ingredient in a mixture containing 70 wt % of cyclohexanone, 20 wt % of Nekanil.RTM. LN (=Lutensol AP6, a spreader-sticker with an emulsifying and dispersing action based on ethoxylated alkylphenols) and 10 wt % of Emulphor.RTM. EL (an emulsifier based on ethoxylated fatty alcohols). The concentrations given in the examples were obtained by diluting the formulated active ingredient with water.

Contact Action on Oriental Cockroaches (Blatta orientalis)

The bottoms of 1-liter jars were treated with acetonic solutions of the active ingredients. After the solvent had evaporated, 5 adult cockroaches were placed in each jar. The kill rate was determined after 48 hours.

In this experiment, compound no. 1.1 had an activity ten times greater than that of comparative substance I. Comparative substance II was ineffective at a concentration of 1 mg.

Contact Action on Sitophilus granaria (Granary Weevil)

The bottoms of glass Petri dishes 10 cm in diameter (the rims of which had been treated with FLUON) were treated with 1 cm.sup.3 of acetonic solutions of the active ingredients. After the acetone had evaporated, about 50 weevils were introduced into each dish.

After 4 hours, the weevils were transferred to cardboard dishes 40 mm in diameter and 10 mm high, which were then placed in the Petri dishes. The action was determined after 24 hours in percentage kill.

Weevils unable to leave the cardboard dishes were considered to be dead or heavily damaged.

In this experiment, compound 1.1 was superior to comparative substance I, and comparative substance II was ineffective at a concentration 10 times higher than the inventive compound.

Contact Action on Aedes aegypti (Yellow-fever Mosquito)

At 25.degree. C., 200 ml of tapwater containing the active ingredients was filled into 250 ml plastic beakers; 20 to 30 mosquito larvae in the third to fourth larval stage were then introduced. The temperature was kept at 25.degree. C. The action was assessed after 24 hours.

In this experiment, compound 1.1 was far superior to the comparative substances.

Continuous Contact Action on Musca domestica (Housefly)

Both the tops and bottoms of Petri dishes 10 cm in diameter were lined with a total of 2 ml of acetonic solutions of the active ingredients. After the solvent had evaporated (about 30 mins.), 10 flies were introduced into each dish. The kill rate was established after 4 hours.

In this experiment, compound 1.1 was superior to comparative substances I and II.

Contact Action on Prodenia litura

Glass Petri dishes 10 cm in diameter were treated with acetonic solutions of the active ingredients. After the solvent had evaporated, 5 caterpillars in the fourth larval stage were introduced and the dishes closed. The kill rate was assessed after 4 hours.

In this experiment, compound 1.1 was superior to comparative substance II. Comparative substance I achieved 0% kill at the higher concentration of 1 mg.

Contact Action on Plutella maculipennis (Diamondback Moth)

Leaves of young cabbage plants were dipped for 3 seconds into aqueous emulsions of the active ingredients and placed, after excess liquid had been briefly allowed to drip off, on a moist filter paper in a Petri dish. 10 caterpillars of the fourth stage were placed on each leaf. The kill rate was determined after 48 hours.

In this experiment, compound 1.1 had a 50 times higher activity than comparative substance I.

Contact Action on Ornithodorus moubata (Tick)

Young ticks (1.5 to 2 mm in diameter) which had sucked blood once were individually picked up by means of a suction tube. A strong light source drove the active animals from the discarded exoskeleton remains.

5 ticks were placed in paper bags, and the bags were dipped for 5 seconds in aqueous active ingredient formulations. The bags were then suspended and the action was assessed after 48 hours by holding the bags up to a strong light source; the animals still living tried to evade the light and were easy to recognize from their movements.

In this experiment, compound 1.1 had an activity 20 times higher than comparative substance I and 40 times higher than comparative substance II.
