资源简介：
Treatment of [Cp2Ln(μ-SEt)]2 with PhRCCO gives dimeric complexes [Cp2Ln(μ-η1:η2-OC(SEt)CPhR)]2 [R = Ph, Ln = Yb (1), Er (2), Sm (3), Y (4); R = Et, Ln = Er (5)], which
represent the first example of ketene insertion into a metal−sulfur bond and provide an
efficient method for the synthesis of organolanthanides with a β-thiolate-substituted enolate
ligand. It is found that an excess of ketene does not affect the nature of the final complexes,
with only a single insertion being observed. All these complexes are characterized by
elemental analysis and spectroscopic properties. The structures of complexes 1·C6H5CH3,
2·C6H5CH3, and 5·THF are determined through single-crystal X-ray diffraction analysis.
