Abstract

Two new routes to 1, 2-dichloro-1, 2-bis-(polyfluoroalkyl)-ethylenes are presented. These routes involve coupling of l, l, l-trichloropolyfluoroalkanes with copper, and reaction of a fluorinated acid chloride with l, l-dichloro-2, X-difluoroethylene and nickel carbonyl. Dechlorination of two of the dichlorodefins to produce new Isis-(polyfluraroalky1)-acetylenes is tlescribed.
