Addition to a carbonyl by a semi-anionic hydride, such as NaBH 4, results in conversion of the carbonyl compound to an alcohol. The hydride from the BH 4- anion acts as a nucleophile, adding H - to the carbonyl carbon. A proton source can then protonate the oxygen of the resulting alkoxide ion, forming an alcohol.
