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.
