    Abstract: PCT No. PCT/EP95/04463 Sec. 371 Date May 6, 1997 Sec. 102(e) Date May 6, 1997 PCT Filed Nov. 14, 1995 PCT Pub. No. WO96/16023 PCT Pub. 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.

    Abstract: A process is disclosed for preparing halogenated methyl benzoyl cyanides having the formula (I): PH-CO-CN, in which Ph stands for a phenyl rest substituted by chloromethyl or bromomethyl that may optionally carry 1-4 other rests, from halogenated methyl benzoyl chlorides having the formula (II): PH-CO-Cl. The compound having the formula (II) is reacted with a cyanide-releasing compound in the presence of a Lewis acid, optionally in an inert organic solvent or diluent, and the product obtained by this process is then isolated. The halogenated methyl benzoyl cyanides having the formula (I) are important intermediate products for the synthesis of plant protective agents.

    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.
