Synthesis of gem-dihaloenynes and butatrienes from gem-dihalovinyl derivatives
摘要:
gem-Dihaloenynes were synthesized in high yields from 1,1,4,4-tetrahalo-1,3-butadienes through the Fritsch-Buttenberg-Wiechell (FBW) rearrangement mediated by an organolithium compound. Butatriene derivatives could be obtained efficiently via an organolithium-mediated reaction of o-halo-(2,2-dihalovinyl)benzenes. (C) 2012 Elsevier Ltd. All rights reserved.
