Palladium-Catalyzed C–H Allylation of Electron-Deficient Polyfluoroarenes with gem-Difluorinated Cyclopropanes

Abstract

A palladium-catalyzed C-H allylation of electron-deficient polyfluoroarenes with gem-difluorinated cyclopropanes is reported. It provides a useful and facile approach to 2-fluoroallylic polyfluoroarenes in moderate to excellent yields with high Z-selectivity. In addition, this new approach has good functional group compatibility and broad substrate scope.
