    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 2-chloromethylphenyl acetic acid derivatives of formula (I), in which X represents C1-C4 alkoxy or methylamino, by cleaving the ether bonds in compounds of formula (II), in which R represents C1-C4 alkyl, C1-C4 alkoxy, C1-C2 alkyl halide, C1-C4 alkylcarbonyl, C1-C4 alkylcarbonyloxy, halogen, nitro or cyano, and X has the above-mentioned meaning. The inventive method is characterized in that the transformation takes place in the presence of hydrogen chloride and of an inert solvent, and in that a catalyst selected from the group comprised of: iron, indium or halogenides, oxides or triflates thereof is added to the reaction mixture.

Date May 30, 1996Halomethylbenzoyl cyanides I PH-CO-CN (I) where Ph is phenyl which is substituted by chloromethyl or bromomethyl and may cary 1-4 other rradicals, are prepared from halomethylbenzoyl chlorides II PH-CO-Cl (II), by reacting II with a cyanide-donating compound in the presence of a Lewis acid, if required in an inert organic solvent or diluent, and then isolating the product. The halomethylbenzoyl cyanides I are important intermediates for synthesizing crop protection agents.
