(Imido)vanadium(V) complexes containing the (2-anilidomethyl)pyridine ligand, V(NR)Cl2[2-ArNCH2(C5H4N)] (R = 1-adamantyl (Ad), cyclohexyl (Cy), phenyl), exhibit remarkably high catalytic activities (e.g. TOF = 2-730-000 h-1 (758 s-1) by V(NAd)Cl2[2-(2,6-Me2C6H3)NCH 2(C5H4N)) for ethylene dimerization in the presence of MAO, affording 1-butene exclusively (selectivity 90.4 to >99%). The steric bulk of the imido ligand plays an important role in the selectivity (polymerization vs dimerization), and the electronic nature directly affects the catalytic activity (activity: R = Ad > Cy > Ph).

Vanadium nitrido complexes are generally not accessible by routes successful in rhenium and molybdenum chemistry.The vanadium-nitrogen triple bond is reactive, and easily forms phosphiniminato complexes, two of which and V(NPMe2P
