Abstract: The invention relates to a method for producing o-chloromethyl benzoic acid chlorides of formula (I), in which R 1 to R 4 can be the same or different and represent hydrogen C 1 -C 4 alkyl, halogen or trifluoromethyl, by reaction benzo condensed lactones of formula (II), in which R 1 to R 4 have the above-mentioned meaning, with thionyl chloride. The inventive method is characterized in that the reaction is carried out in the presence of catalytic quantities of a Lewis acid and in the presence of catalytic quantities of a phosphine derivative.

Abstract: The invention relates to a method for producing oxime ethers of formula (I), in which the substituents R1 and R2 can be identical or different and can respectively represent cyano, alkyl, haloalkyl, cycloalkyl, phenyl and naphthyl and R3 can represent alkyl, by the alkylation of oximes of the formula (II), under alkaline conditions, using an alkylation agent from the group containing alkyl halides, dialkyl sulfates and dialkyl carbonates. The reaction is carried out in a mixture consisting of between 5 and 25 wt.- % polar aprotic solvents, selected from the group containing nitriles, N- alkylpyrrolidones, cyclic urea derivatives, dimethylformamide and dimethylacetamide, between 55 and 95 wt.- % non-polar solvents, selected fro m the group containing aliphatic hydrocarbons, aromatic hydrocarbons, alkyl esters of alkyl carboxylic acid and ethers and between 0 and 25 wt.- % water , whereby the sum of said proportions amounts to 100 %.

Abstract: The invention relates to a method for producing o-choromethyl benzenecarbonyl chlorides of formula (I), wherein R -R can be the same or different and stand for hydrogen, C1-C4-alkyl, halogen or trifluoromnethyl, by converting benzocondensed lactones of formula (II), wherein R -R have the aforementioned meaning, with gaseous or liquid phosgene and the dimers or trimers thereof. The inventive method is characterized in that the conversion is carried out in the presence of catalytical amounts of a Lewis acid and catalytical amounts of a phosgenation catalyst

Abstract: A process for preparing halomethylbenzoyl cyanides I Ph-CO-CNI (Ph=phenyl radical substituted by chloromethyl or bromomethyl which, if desired, can additionally carry 1-4 further radicals) by reacting halomethylbenzoyl chlorides II Ph-CO-ClII with an alkali metal cyanide or transition metal cyanide, if appropriate in an organic diluent, and novel halomethylbenzoyl cyanides I' I' (X=halogen, C1-C4-alkyl, C1-C4-alkoxy, CF3, C1-C5-alkyl-(C1-C5-alkyl)hydroxyimino or C1-C5-alkyl-(C2-C5-alkenyl)hydroxyimino; m=0 to 4 and Y=chloromethyl or bromomethyl) are described. The halomethylbenzoyl cyanides I are important intermediates for the synthesis of plant protection agents.
