Carbonyl to alcohol reduction

WebThe carbonyl reforms with the loss of the alkoxide leaving group. The alkoxide then deprotonates the resulting carboxylic acid. The complete mechanism is shown below. 1) Nucleophilic reaction by hydroxide 2) Leaving group removal 3) Deprotonation Nuclephilic Acyl Substitution Reactions from Esters WebBiological Reduction Addition to a carbonyl by a semi-anionic hydride, such as NaBH 4, results in conversion of the carbonyl compound to an alcohol.
