本文介绍了一系列(亚胺)钒(V)-烷基配合物的合成及其与醇(酚)反应的最新结果，这些反应被认为是通过涉及醇(酚)配位的中间体进行的。在中性配体(PMe3等)存在下，通过α-氢消除法制备的(亚胺)钒(V)-亚烷基配合物，即使在高温下也表现出较高的环烯烃(降冰片烯)开环歧化聚合活性，这对钒配合物催化烯烃歧化反应具有良好的应用前景。
This minireview introduces recent results in the synthesis of a series of (imido)vanadium(V)-alkyl complexes, and some reactions with alcohols (phenols) that are proposed to proceed via intermediates involving coordination of the alcohols (phenols). (Imido)vanadium(V)-alkylidene complexes, prepared by α-hydrogen elimination in the presence of a neutral donor ligand (PMe3, etc.), exhibited high activity for ring-opening metathesis polymerisation of cyclic olefins (norbornene) even at high temperature; these are promising for olefin metathesis by vanadium complex catalysts.
