资源简介：
Two different heteroditopic bis(aryl)-substituted imino-N-heterocyclic
carbene ligands were coordinated to nickel using new copper carbene
dimers as transmetalating agents. The oxidative addition of an imidazolium
salt precursor with Ni(COD)2 led to the unexpected bis(carbene)NiCl2 complex, presumably through a putative nickel hydride intermediate.
All new complexes were isolated in good yield and were structurally
characterized. The size of the iminic carbon substituent was found
to have a profound impact on the bond angles and bond lengths about
the metal center. All nickel complexes were tested for ethylene polymerization
activity at standard temperature and pressure and were found to be
inactive.
