<i>gem</i>-Difluorovinylation of alkynyl bromoarenes<i>via</i>dual nickel-/palladium-catalyzed cross-electrophile coupling

Abstract

A dual nickel-/palladium-catalyzed gem -difluorovinylation of alkynyl bromoarenes is presented. This method proceeds smoothly to afford various dihydrobenzofuran compounds containing gem-difluorovinyl fragments with excellent stereoselectivities.
