The reaction between tungsten(VI) complex [W(eg)(3) (eg = 1,2-ethanediolato dianion) and a phenolic ligand precursor 2,4-di-tert-butyl-6-(((2-hydroxyethyl)(methyl)amino)methyl)phenol (H(2)L) affords a monomeric oxcitungsten complex [WO(eg)(L)]. This complex reacts further with Me(3)SiCl, which leads to the displacement of ethanediolato ligand from the complex unit and formation of cis- and trans-isomers of corresponding dichloro complex [WOCl(2))(L)]. Identical dichloro complexes were also prepared by the reaction between H(2)L and WOCl(4). Molecular structure of [WO(eg)(L)] was verified by X-ray crystallography. (C) 2008 Elsevier B.V.
