  Insertion of ketenes into lanthanocene n-butylamide and imidazolate complexes

  摘要：

  Reaction of Cp(2)LnNH(n)Bu with 1 equiv. of Ph2CCO in toluene affords dimeric complexes [Cp(2)Ln(OC(CHPh2)(NBu)-Bu-n)](2) [Ln = Yb (1), Dy (2)], derived from a formal insertion of the C=C bond of the ketene into the N-H bond. Treatment of CpErCl2 with 2 equiv. of (LiNHBu)-Bu-n followed by reacting with Ph2CCO affords a rearrangement product [Cp2Er(OC(CHPh2)(NBu)-Bu-n)](2) (3). Treatment of [Cp(2)Ln(mu-Im)](3) (Im = imidazolate) with PhRCCO gives [Cp(2)Ln(mu-OC(Im)=CPhR)](2) [R = Et, Ln = Yb (4); R = Ph, Ln = Yb (5), Er (6)]. In contrast to the previous observations that [(Cp2ErNPr2)-Pr-i](2) and [Cp2ErNHEt](2) react with ketenes to give di-insertion products, in the present cases the presence of excess of ketenes has no influence on the final product even with prolonged heating and only monoinsertion products are isolated. All these complexes were characterized by elemental analysis, IR and mass spectroscopies. The structures of complexes 1 and 3-6 were also determined through X-ray single crystal diffraction analysis.
