英文摘要: A new approach for the synthesis of gem-difluorostyrenes from benzyl bromide is described. Quatemization of triphenylphosphine with benzyl bromide to give phosphonium salts, deprotonation of the corresponding phosphonium salts to produce phosphonium ylide, and the subsequent olefination of phosphonium ylide with difluorocarbene generated from difluoromethylene phosphobetaine (Ph3P+CF2CO2-) by decarboxylation can occur smoothly in one-pot, furnishing the final gem-difluorostyrenes in good yields.
