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.
