At –78°C [W(NPh)(CH2SiMe3)3Cl] reacts with 2-[(dimethylamino)methyl]phenyllithium in diethyl ether to produce a tetra-organotungsten(VI) complex which decomposes by an Hα-elimination reaction generating a novel tungsten(VI) alkylidene with intramolecular coordination of an amine function; this complex reacts with norbornene to provide a cis-polymer that is the result of a selective ring-opening metathesis
