Early–Late Heterobimetallic Complexes with a Ta–Ir Multiple Bond: Bimetallic Oxidative Additions of C–H, N–H, and O–H Bonds
摘要:
A heterobinuclear transition metal complex with a Ta-Ir multiple bond, Cp*(Me3SiCH2)(2)Ta-IrCp*(H)(2) (1), was synthesized using a salt elimination reaction. The isolable complex was characterized by NMR, IR, UV-vis spectroscopy, and X-ray crystallography. Compound I features an exceptionally short intermetallic distance (Ta-Ir 2.4457(3) angstrom). DFT calculation for 1 revealed the presence of a highly covalent bonding nature in spite of the involvement of such disparate d elements. Oxidative additions of C-H, N-H, and O-H bonds to 1 were also investigated.
