Novel fluorous alkenyl-fluorosilanes (V) are synthesized by a three-step procedure and subjected to a Hiyama coupling reaction with iodobenzene to provide the appropriate ω-perfluoroalkyl-styrenes. In general, the reaction of (Va) with o-substituted iodobenzene fails, while m-and p-substituted iodobenzenes give rise to formation of fluorous styrenes in low to high yields. The mechanism of the coupling reaction is a pure Hiyama-type one involving fluoride-ion induced transmetalation without Heck-type contribution. -(RABAI*, J.; CSAPO, A.; BODOR, A.; J.
