(Arylimido)vanadium(V)–alkylidene complexes, V(CHSiMe<sub>3</sub>)(<i>N</i>-2,6-X<sub>2</sub>C<sub>6</sub>H<sub>3</sub>)(OC<sub>6</sub>F<sub>5</sub>)(PMe<sub>3</sub>)<sub>2</sub> [X = Me (<b>2</b>), Cl (<b>4</b>)], exhibited remarkable catalytic activities for ring-opening metathesis polymerization (ROMP) of norbornene, and the ROMP by <b>2</b> proceeded in a living manner, affording ultrahigh molecular weight polymers. <i>Cis</i>-specific ROMP was achieved with the alkoxo analogues, V(CHSiMe<sub>3</sub>)(<i>N</i>-2,6-X<sub>2</sub>C<sub>6</sub>H<sub>3</sub>)[OC(CH<sub>3</sub>)(CF<sub>3</sub>)<sub>2</sub>]-(PMe<sub>3</sub>)<sub>2</sub> [X = Me (<b>5</b>), Cl (<b>6</b>)]. Both the activity and the selectivity increased upon additio...
