摘要：

The novel silicon-, germanium- and tin-containing imido alkyl complexes of tungsten of the type (ArN)(2)W(CH2EMe3)(2) (Ar = 2,6-(Pr2C6H3)-C-i; E = Si (1), Ge (2), Sn (3)) have been prepared by the reactions of (ArN)(2)WCl2(dme) (dme = 1,2-dimethoxyethane) with heteroelement-containing alkyllithium or Grignard reagents Me3ECH2Li (E = Si, Ge), Me3ECH2MgCl (E = Ge, Sn). The title compounds were isolated in high yields as crystalline solids and characterized by elemental analysis, IR, H-1, C-13, Si-29 and Sn-119 NMR spectroscopy and X-ray diffraction studies. The geometry of the W atoms in the compounds can be described as a distorted tetrahedron. (c) 2005 Elsevier B.V. All rights reserved.
