Abstract

Reaction of [WCl₄(O)] with either o-C₆H ₄(CH₂MgCl)₂ or Mg{(CH₂) ₂C₆H₄-o}(thf) in tetrahydrofuran (thf) gives the W^v complex [{W(CH₂C₆H₄CH ₂-o)₂-O}₂ Mg(thf)₄], (1) via W ^v oxochloride intermediates; single crystal X-ray diffraction of the complex (1) shows that one of the o-xylidene chelating ligands has a large fold angle (66.1°, cf. 42.4° for the other) possibly owing to an aromatic π-interaction with the tungsten atom.
