Description and Uses
Benzal chloride (dichloromethylbenzene, a,adichlorotoluene, benzylidene chloride) is produced exclusively by the side-chain chlorination of toluene. It was first synthesized in 1848 by A. CAHOURS, by using the reaction of PCl5 with benzaldehyde. Almost the sole application of benzal chloride is in the production of benzaldehyde.
α,α-Dichlorotoluene has been useds as initiator during the atom transfer radical polymerization (ATRP) of styrene and methyl methacrylate.
