Palladium-catalyzed synthesis of monofluoroalkenes from 3,3-difluoropropenes using dimethylmalonate and derivatives as nucleophiles.

The synthesis of monofluoroalkenes bearing a malonate or its derivatives at the β position is presented. The reaction can be performed with various 3,3-difluoropropenes. A preliminary result for an enantioselective variant is also reported. Further synthetic transformations of a monofluoroalkene were also accomplished.
