Abstract: The halogenated methyl benzoyl cyanides are of formula (I) Ph-CO-CN , in which Ph stands for a phenyl rest substituted by chloromethyl or bromethyl that 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, 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 synthesys of plant protective agents.
