Abstract

Although it is known that dialkylzinc reagents, R2Zn, are generally inert to carbonyl compounds, addition of a catalytic amount of an amino alcohol1 or certain transition metal complexes2 can enhance their nucleophilicity and make them reactive toward carbonyl compounds. It is reported that R2Zn can reduce vanadium (IV) complexes and produce low- valent vanadium (II) species, 3 but application of the latter to organic synthesis has not ...
