Synthesis of Dinuclear Complexes Bearing Metalloporphyrin−Phosphine Hybrid Ligands and Their Catalytic Activity toward Hydrosilylation of Ketones
摘要:
A new type of metalloporphyrin-phosphine hybrid ligand (1) has been designed and synthesized. Reactions of some transition metal complexes such as PdCl2, PtCl2, and [RhCl(CO)(2)](2) with a zinc porphyrin-phosphine ligand (1; M-1 = Zn) afford the corresponding dinuclear complexes (2) bearing the hybrid ligand. The zinc porphyrin-phosphine compound (1; M-1 = Zn, R = Ph) has been found to work as an effective ligand for Rh(I)- or Ir(I)-catalyzed hydrosilylation of ketones to give the corresponding alcohols after acid hydrolysis.
