Abstract
Novel tungsten(VI) complexes of the type WOCl3L and WO2L2 [L = 2'-pyridylal coholate] are formed from WOCl4 or WO2Cl2, respectively, and 2'-pyridyl alc ohols; the dioxotungsten(VI) complexes (characterised by X-ray crystallogra phy) can also be obtained from WO2(acac)(2) by ligand exchange; they repres ent catalysts with remarkable activity and excellent product selectivity in olefin epoxidation.
