Alkoxides and Alkylamides

Carbanions, alkoxides and alkylamides all behave as reducing agents under appropriate circumstances. The effect of hyperconjugative interaction between a C—H bond and negative charge on an adjacent atom has already been noted, and, in most but not all cases, the reductions are accommodated within the framework of hydride transfer from an activated C—H bond to an electrophile, usually carbonyl carbon.
