Derivatives of fluorinated alkenes are commonly found in biologically active molecules, but their synthesis remains challenging. Towards this goal, a rhodium-catalysed method for the selective β- or γ-addition of nucleophiles to gem-difluoroallenes has now been developed. Catalysts with N- or P-based ligands result in the β- or γ-selective addition, respectively, of amines and thiols to gem-difluoroallenes.
