Procedure

Finally the art teaches in U.S. Pat. No. 2,780,604 that chloromethyl vinyl benzene can be prepared via a two step liquid phase reaction whereby isopropyl toluene is chlorinated via ultraviolent light and the subsequently distilled chloromethyl chloroisopropyl benzene is dehydrohalogenated with heat to give chloromethylisopropenylbenzene.
