Convenient preparation and functionalization of 2-metallated pentafluoropropenes
摘要:
The title compounds are prepared by metallation of CF3CH = CF2 with LDA or t-BuLi or by metallation of CF3CBr2CF3 with 2 equivalents of zinc. CF3C(ZnX) = CF2 undergoes halogenation, oxidative dimerization, allylation and acylation reactions.
