This article summarizes recent efforts for synthesis and reaction chemistry with (imido)vanadium(V)‐alkyl, ‐alkylidene complexes. These (arylimido)vanadium(V) dichloride complexes especially containing aryloxo ligands exhibited notable activities for ethylene polymerization affording ultra high molecular weight polymers with unimodal molecular weight distribution, and the reacition pathways for the polymerization/dimerization using (imido)vanadium(V) dichloride complexes containing (2‐anilido‐methyl)pyridine ligands can be tuned by modification of the steric bulk in the imido substituents; the adamantylimido analogues exhibited exceptionally high both activity and selectivity in the dimerization. This article entitled “ (Imido)Vanadium(V)‐Alkyl, Alkylidene Complexes Exhibiting Unique Reactivities towards Olefins, Phenols, and Benzene via 1,2‐C‐H Bond Activation” was contributed by Prof. Kotohiro Nomura who was invited as a Visiting Lecturer (Mar. 6, 2011 ∼Mar. 12, 2011) of the Chemistry Research Promotion Center, Taiwan, R.O.C.
