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. Evidence for a radical based mechanism involving nickel(I) and nickel hydrido complexes as key intermediates was obtained in the corresponding stoichiometric reactions.
含有NNN钳形配体的氟化镍（II）配合物被发现是偕二氟环丙烷加氢脱氟反应的催化剂，该反应会开环形成相应的单氟烯烃，产率良好且Z选择性高。在相应的化学计量反应中获得了涉及镍（I）和氢化镍配合物作为关键中间体的基于自由基机制的证据。
