Two new tungsten(VI) complexes of the type WO2(ONNOR) (ONNOR = tetradentate diaminobis(phenolate) ligand) were prepared by the reaction of trisdiolatetungsten(VI) complex W(eg)(3) (eg = 1,2-ethanediolate) and diaminobis(phenol)s in the presence of water. Studied complexes catalysed ROMP of norbornene when activated by Et2AlCl. They also catalysed oxotransfer reaction between DMSO and benzoin. (C) 2004 Elsevier B.V. All rights reserved.
