A new method for converting benzyl and benzal chlorides to benzotrichlorides is reported. In contrast to prior art, the process involves contacting the substrates with strong alkali in a two-phase system containing phase transfer catalyst using organic soluble perchloralkanes acting upon base-generated carbanions. The method is particularly useful for preparing benzotrichlorides substituted by either alkyl or nitro groups.
