Abstract

Polychloroalkenyl aromatic compounds as exemplified by (1,3-dichloroallyl)benzene are prepared by the condensation of chloroalkyl aromatic compounds such as benzyl chloride with polychloroalkene compounds characterized by the presence of at least one chlorine atom on each of the doubly-bonded carbon atoms in the presence of a free radical-generating compound and a hydrogen chloride compound to produce the desired product.
