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.
