Phosphine-Free NNN Bis-Iminopyridine Supported Zinc(II) Catalysts: A Sustainable Platform for C─C Bond Formation Reactions via Borrowing Hydrogen Approach of Primary Alcohols.
In this study, we present a methodology for direct C─C bond formation using renewable primary alcohols as alkylating agents, catalyzed by base metal-derived Zn(II) complexes. We utilized two well-defined phosphine-free NNN bis-iminopyridine pincer ligands (L1 and L2) for the synthesis of zinc(II) catalysts C1 and C2, w...
