| 摘 要： | 1 INTRODUCTION The insertion of unsaturated molecules into the lanthanide-ligand bond has attracted considerable attention, because it is a fundamental step for many metal-promoted transformations, in which some va- luable new methods for the formation of carbon- carbon and carbon-heteroatom bonds can be deve- loped and some complexes with novel structures or peculiar characters can be obtained[1~4]. Notably, in contrast to the wide reaction chemistry of organo- lanthanide alkyl (aryl), am…

| Abstract: | Treatment of Cp3Y with EtSH, followed by reaction with an equivalent of PhNCO, yielded the dinuclear complex [Cp2Y(μ-η1:η3-OC(SEt)NPh )]2. The structure was characterized by elemental analysis, IR, MS and single-crystal X-ray diffraction analysis. The title compound crysta- llizes in triclinic, space group P(1-) with a = 8.643(3), b = 10.752(4), c = 11.161(4)(A), α= 117.840(5), β= 94.086(5),γ= 101.008(5)°, V = 884.8(6)(A)3, Z = 1, Mr = 798.66 (C38H40N2O2S2Y2), λ(MoKα) = 0.710730(A),μ= 3.417 mm-1, Dc = 1.499 g/cm3, F(000) = 408, the final R = 0.0453 and wR = 0.1007 for 3067 unique reflections (Rint = 0.0317) with 2357 observed ones (I >2σ(I)). X-ray analysis reveals an unusual bonding mode of the OC(SEt)NPh ligand and the OCN fragment acts as a both bridging and side-on chelating ligand. Each yttrium atom is coordinated by two η5-cyclopentadienyl groups, one chelating η3-OC(SEt)NPh ligand and one bridging O atom from another η3-OC(SEt)NPh ligand. |
