Group III Hydride-Donor Reagents

Comparative Reactivity of Common Hydride Donor Reagents [Pg.396]

The mechanism by which the Group III hydrides effect reduction involves activation of the carbonyl group by coordination with a metal cation and nucleophilic transfer of hydride to the carbonyl group. Hydroxylic solvents also participate in the reaction,59 and as reduction proceeds and hydride is transferred, the Lewis acid character of boron and aluminum becomes a factor. [Pg.396]
