N-Fluoroallyl hydrazones with four-ring structure were effectively synthesized using cyclobutanone hydrazones and gem-difluorocyclopropanes as raw materials through palladium catalyzed ring opening of difluorocyclopropanes and nucleophilic capture process of nitrogen nucleophile. This protocol shows broad substrate scope and good functional group tolerance, which can be applied for gram-scale preparation.

Key words: cyclobutanone hydrazone, gem-difluorocyclopropane, ring opening reaction, monofluoroalkene
