Nickel(II) fluorido complexes bearing NNN-pincer ligands were found to be catalysts in the hydrodefluorination of geminal difluorocyclopropanes which undergo ring-opening to form the corresponding monofluoroalkenes in good yield and high Z-selectivities.

motifs, in particular, chiral fluorine molecules with two contiguous stereogeniccenters, has attracted much interest in research due to the limited number of methods available for their preparation. Herein, we report an atom-economical and highlystereoselective synthesis of chiral fluorine molecules with two contiguous stereogeniccenters via azabicyclo iridium-oxazoline-phosphine-catalyzed hydrogenation
