ZOH II
with a lactone of the general formula III ##STR6## where X and m have the abovementioned meanings, if appropriate in the presence of a base or of a diluent or of a mixture thereof.
o-Iminooxymethylbenzoic acids are described in EP 234,045 (p. 97 ). The synthesis there starts from benzyl bromide i, which can be prepared in turn from methyl o-methylbenzoate by bromination according to methods known per se (see Organikum, p. 212) and which is then reacted with the salt of an oxime (EP 234,045, p. 97). In the last step, the ester group is hydrolyzed in the customary manner to liberate the acid. ##STR7##
The preparation and reaction of the benzyl bromide i are particularly a problem. In particular on the large scale, working with bromine or N-bromosuccinimide is complicated and troublesome. Bromine-containing waste products furthermore have to be disposed of.
This method of preparation has the crucial disadvantage of being a long and multi-step process. The yields, in particular the space-time yield, are poor. As a result of this, the preparation of the intermediates of the formula I by the known process is very troublesome, undesired waste products being produced.
It is an object of the present invention to prepare the compounds I in an industrially more practicable way.
We have found that this object is achieved by the process described above.
The invention further relates to a process for preparing an o-iminooxymethylbenzoic acid I, wherein
a) an oxime of the general formula II is converted into the corresponding salt by means of a base in the presence of a diluent,
b) this salt is mixed with a lactone of the general formula III ##STR8## and
c) the mixture is further reacted in solution at from 20.degree. to 250.degree. C., or
d) the diluent is distilled off and the mixture is reacted in the molten state at from 50.degree. to 250.degree. C.
Useful bases are in particular alkali metal hydroxides such as sodium hydroxide and potassium hydroxide and alkali metal alkoxides and alkaline earth metal alkoxides such as sodium methoxide, sodium ethoxide and potassium methoxide and metal hydrides such as sodium hydride; the alkali metal alkoxides and the metal hydrides are particularly preferred.
As a rule, process step (a) is carried out in the presence of a solvent or diluent, the reaction temperature normally being from 0.degree. to 100.degree. C., preferably from 20.degree. to 80.degree. C.
Suitable solvents or diluents are aromatic hydrocarbons such as benzene, toluene and o-, m- or p-xylene, alcohols such as methanol, ethanol and isopropanol, ethers such as dimethoxyethane or tetrahydrofuran, or liquids such as acetonitrile, dimethylformamide, N-methylpyrrolidone, dimethylpropyleneurea or mixtures of said solvents. Methanol and ethanol, dimethylformamide and N-methylpyrrolidone are particularly preferred.
The amount of base is not critical. For complete conversion of the oxime II to the corresponding salt (oximate) at least equimolar amounts of base are required; preferably an excess of 1 to 6 mol % of base are used, based on the amount of lactone III.
The salts of the oxime (oximate) II are advantageously mixed with the lactones of the formula III without isolation from the reaction mixture and fused together with simultaneous removal of the solvent or further reacted in the diluent.
In general, process step (d) is carried out at from 50.degree. to 250.degree. C., preferably from 160.degree. to 200.degree. C. In this process, with a decreasing amount of diluent the lactone III is converted from the dissolved to the liquid state and a readily miscible solution of the oximate in the lactone III is obtained.
Process step (c) is carried out at from 50.degree. to 200.degree. C., preferably from 60.degree. to 160.degree. C.
Normally, the oximate and lactone are employed in an approximately stoichiometric ratio, but in some cases an excess of one or the other component, for example up to 10 mol %, may be advisable.
In process steps (a) to (d), no particular conditions with respect to the pressure are necessary; the process is therefore expediently carried out at atmospheric pressure.
After the reaction has ended, the reaction mixture or the melt is diluted with water. The solution obtained is acidified, preferably with an inorganic acid such as hydrochloric acid or sulfuric acid, to liberate the o-iminooxymethylbenzoic acid I. Further working-up is carried out in the customary manner.
The compounds of the formula I prepared by the process according to the invention can basically be obtained as E/Z mixtures with respect to the C.dbd.N double bond if R.sup.1 and R.sup.2 are different. As a rule, however, far more predominantly, if not exclusively, only one isomer is obtained if R.sup.1 and R.sup.2 are sterically sufficiently different.
The process according to the invention can be carried out either batchwise or continuously. In the continuous procedure, the reactants are passed, for example, through a tubular reactor or over stirring vessel cascades.
The preparation method described can be used successfully for the synthesis of the o-iminooxymethylbenzoic acids of the formula I defined, in particular for those compounds in which the substituents R.sup.1, R.sup.2, X and m have the following meanings:

The o-iminooxymethylbenzoic acids of the formula I are surprisingly obtained in high yield and excellent purity by the process according to the invention. This was not to be expected from the prior art. In particular, it was in no case to be foreseen that the salt of the oxime (oximate) could be reacted readily in this reaction at high temperatures (100.degree.-160.degree. C.) without decomposing. Compared to the prior art, the process according to the invention has a number of advantages. It can be carried out in a very simple manner on the industrial scale. It does not require the use of bromine or possibly chlorine or N-bromosuccinimide or N-chlorosuccinimide. It thus avoids the formation of halogen-containing waste products and is therefore industrially simpler and fairly problem-free. Corrosion problems due to halogen are additionally avoided. A significant advantage of this process is furthermore that it leads to the acids of the formula I in a one-step, industrially simple and problem-free process.
A further advantage is that in one variant of the process the alkali metal oximate produced as an intermediate does not have to be isolated as a solid, but that a fluid transition from a solution or suspension of the oximate from the diluent to the melt (oximate+lactone III) takes place. This is achieved by adding the lactone III to the salt of the oxime II in the presence of a diluent and then distilling off the diluent.
In another variant, the oximate can be further reacted with the phthalide in a solvent. The flexibility of the reaction procedure in the context indicated enables the optimum conditions to be selected for the particular individual case.
The o-iminooxymethylbenzoic acids I are useful intermediates for preparing o-iminooxymethylphenyl esters IX and X, which are used in plant protection, in particular as fungicides [cf. EP-A 370,629; EP-A 414,155; EP-A 426,460; EP-A 460,575;. WO 70/07493). ##STR10##
In the following reaction scheme, two particularly preferred synthetic routes for preparing the compounds IX from o-iminooxymethylbenzoic acid are shown: ##STR11##
The benzoic acids I are advantageously converted into their acid chlorides by this process (cf. Organikum, VEB Deutscher Verlag der Wissenschaften, 16th edition, Berlin, 1986, page 423 et seq.) and the corresponding benzoyl cyanides VI are prepared from these, using an aqueous organic two-phase system and in the presence of a phase-transfer catalyst [Tetrahedron Letters (1974) 2275].
The benzoyl cyanides IV are then reacted with lower alcohols by the Pinner reaction [cf. Angew. Chemie 94 (1982) 1], phenylglyoxylic acid ester VIII resulting. The .alpha.-ketoesters VIII are then reacted either with o-methylhydroxylamine (or a salt thereof) to obtain the bisoxime ether of the type X, or reacted with a methoxymethylenation reagent such as methoxymethylenetriphenylphosphorane (cf. EP 0,044,448, Jul. 4, 1980) to prepare the acrylic esters IX. In a second known process, the acid I is first converted into its corresponding esters V (cf. Organikum page 499). These esters V are then converted to the .beta.-ketosulfoxide VII in the presence of base and dimethyl sulfoxide (J. Am. Chem. Soc. 88 (1966) 5498). The .alpha.-ketoesters VIII are then obtained by the Pummerer reaction by bromination of the compound VII in the presence of a base and rearrangement in an acid (cf. J. Am. Chem. Soc. 88 (1966) 5498 and Synthesis (1982) 41).
