发明名称 Synthesis of alpha, beta, beta-trifluorostyrene via in-situ formation of trifluorovinyl metal halide
摘要 alpha,beta,beta-Trifluorostyrene and derivatives thereof synthesized in two steps from 1,1,1,2-tetrafluoroethylene. In the first step, 1,1,1,2-tetrafluoroethylene is reacted with a base, a metal salt such as zinc chloride and an optionally amine to form a trifluorovinyl metal complex. In the second step, the trifluorostyrene or derivative is obtained by reacting the trifluorovinyl metal complex with an aryl transfer agent such as, for example, an aryl triflate or an aryl halide, in the presence of a metal catalyst and optionally a coordinating ligand. Both steps may be carried out in one reactor.
