<p>A process for the dehydrohalogenation of a (polyhaloalkyl)benzene containing a benzylic halogen such as 1,3-dichloro-5-(1,3,3,3-tetrachloro-1-methyl-propyl)benzene by contacting the (polyhaloalkyl)benzene with a Lewis acid such as AlCl3 deposited on an inert support such as silica gel or alumina, under conditions sufficient to catalyze said dehydrohalogenation to form a (polyhaloalkenyl)benzene such as 3,5dichloro-.alpha.-(2,2,2-trichloroethyl)styrene. 27,575-F</p> |
