Abstract

A new type of tungsten(VI) alkylidene complex has been prepared with [OCPh2(2-py)], a potentially bidentate O,N-chelating monoanionic ligand, and the corresponding triorganotungsten phenylimido alkoxide precursor complexes have been isolated; the new tungsten(VI) alkylidene complex [W(CHSiMe3)(CH2SiMe3)(NPh)-{OCPh2(2-py)}]3 reacts with norbornene (70 °C) to provide selectively the cis-polymer in a ring-opening metathesis polymerization reaction.
