Compounds containing M-C cr-bonds are frequently unstable and do not give rise to an extensive chemistry (p. 999). Vanadium forms a neutral (paramagnetic) hexacarbonyl which, though not very stable, contrasts with that of titanium in that it can at least be prepared in...

The widely used asymmetrical epoxidation of allylic alcohols developed by Katsuki and Sharpless employs tert-batyl hydroperoxide (TBHP), enantiomerically pure tartaric acid esters, and isopropyl titanium(TV) (6). Similar results were obtained using TBHP and vanadyl acetyl acetonate VO(acac>2 and hexacarbonyl molybdenum [7,8]. The drawback of these reactions are their restriction to allylic alcohols, which is required as anchor group for the formation of the intermediate complex.
