  C-Metalated Diazoalkane Complexes of Platinum Based on PCP- and PCN-Type Ligands

  摘要：

  A series of the first C-metalated diazoalkane complexes of Pt, based on pincer-type PCN and PCP ligands (PCP = C6H3[CH2P(iPr)(2)](2); PCN = C6H3[CH2P(tBu)(2)](CH2)(2)N(CH3)(2)), with the general formula (PCX)Pt[C(N-2)RI (2, X = N, R = Ph; 3, X = N, R = SiMe3; 5, X = P, R = Ph) were prepared via direct nucleophilic attack of RCN2-Li+ at the metal center. These remarkably stable complexes were characterized by H-1, P-31{H-1}, and C-13 NMR and IR spectroscopy. Complex 2 was also characterized by single-crystal X-ray crystallography. Reactions of the C-metalated diazoalkane Pt complexes with Cu(I) (reported to catalyze decomposition of diazoalkanes) were strongly influenced by the nature of the pincer ligand. Bimolecular coupling to generate diphenylacetylene and (PCP)Pt-OTf (6) was observed in the case of the rigid PCP-based complex 5, while the hemilabile PCN-based complex 2 was converted to an ylide-bridged dimeric structure, the formation of which was promoted by the decoordination of the ligand amine arm. In addition, formation of the stable metalsubstituted azine-type binuclear complex 10, generated by reaction of 2 with Rh-2(OAc)(4), is described.
