摘要：

The phenylimino-bridged diphenol PhN(o-C6H4OH)(2) reacts with W(PMe3)(4)(eta(2)-CH2PMe2)H to yield a variety of mononuclear and dinuclear complexes that include [kappa(2)-PhN(C6H4-OH)(C6H3O)] W(PMe3)(4)H-2, [mu-kappa(2), kappa(2)-PhN(C6H3O)(2)]{W-(PMe3) 4H2}(2), [kappa(3)-PhN(C6H4O)(2)] W(PMe3)(3)H-2, [kappa(4)-N(C6H4)-(C6H4O) (2)]W(PMe3)(3)H, and [kappa(2)-PhN(C6H4O)(2)](2)W(PMe3)(2) Via O-H and C-H bond activation reactions. Structural characterization of these compounds by X-ray diffraction demonstrates that the derived alkoxide ligand is structurally flexible and can adopt bidentate, tridentate, and tetradentate coordination modes.
