Recent Advances in Transition-Metal-Catalyzed Cross-Coupling Reactions of gem -Difluorinated Cyclopropanes.

As a special class of cyclopropanes, gem -difluorinated cyclopropanes have many fascinating properties as a result of the gem -difluoro substitution; thus, their reactions have received much attention from the synthetic chemistry community. Recently, gem -difluorinated cyclopropanes have gradually emerged as a type of novel and unique fluorinated allylic synthon in cross-coupling reactions for the synthesis of monofluoroalkenes. Herein, we briefly summarize recent advances in transition-metal-catalyzed reactions of gem -difluorinated cyclopropanes. 1 Introduction 2 Palladium-Catalyzed Reactions with Linear Selectivity 3 Palladium-Catalyzed Reactions with Branched Selectivity 4 Other Metal-Catalyzed Reactions 5 Conclusions [ABSTRACT FROM AUTHOR]
