- 中文摘要: Complex fac-[Fe(CO)3(TePh)3]- was employed as a "metallo chelating" ligand to synthesize the neutral (CO)3Mn(m-TePh)3Fe(CO)3 obtained in a one-step synthesis by treating fac-[Fe(CO)3(TePh)3]- with fac-[Mn(CO)3(CH3CN)3]+. It seems reasonable to conclude that the d6 Fe(II) [(CO)3Fe(TePh)3]- fragment is isolobal with the d6 Mn(I) [(CO)3Mn(TePh)3]2- fragment in complex (CO)3Mn(m-TePh)3Fe(CO)3. Addition of fac-[Fe(CO)3(TePh)3]- to the CpNi(I)(PPh3) in THF resulted in formation of the neutral CpNi(TePh)(PPh3) also obtained from reaction of CpNi(I)(PPh3) and [Na][TePh] in MeOH. This investigation shows that fac-[Fe(CO)3(TePh)3]- serves as a tridentate metallo ligand and tellurolate ligand-transfer reagent. The study also indicated that the fac-[Fe(CO)3(SePh)3]- may serve as a better tridentate metallo ligand and chalcogenolate ligand-transfer reagent than fac-[Fe(CO)3(TePh)3]- in the syntheses of heterometallic chalcogenolate complexes.
