摘要：

Terminal vinyl triflones served as excellent Michael addition acceptors which readily reacted with difluoromethylene phosphabetaine and di- or mono-fluoroalkyl bromides to afford compounds containing CF2 or CF groups. This fluoroalkylation is characterized by mild reaction conditions, ready availability of reagents and excellent functional-group tolerance. (C) 2019 Elsevier Ltd. All rights reserved.
