The gem-difluoroalkene functionality is relevant to drug design as it is a bioisostere of a carbonyl group. Here, the authors report the synthesis of 2,2-difluorovinyl benzoates as versatile building blocks for modular synthesis of gem-difluoroenol ethers and gem-difluoroalkenes by nickel-catalyzed cross coupling.
