“…As a consequence, NHC complexes are more stable towards dissociation or degradation. There have been some reports of NHC metal complexes utilized as catalyst precursors for olefin polymerizations [3][4][5][6][7][8][9]. In this study, we report the preparation, characterization, and olefin polymerization reactivity of g 3 -benzylnickel complexes of the NHC ligands, 1,3-bis-(2,6-diisopropylphenyl)imidazol-2-ylidene (IiPr) and 1,3-bis-(2,6-diisopropylphenyl)imidazolin-2-ylidene (SIiPr).…”
