WebMechanism. This mechanism is for a LiAlH 4 reduction. The mechanism for a NaBH 4 reduction is the same except methanol is the proton source used in the second step. 1) Nucleopilic hydride anion reacts with the electrophilic carbonyl carbon forcing the pi electrons onto the electronegative oxygen atom. 2) The alkoxide is protonated. WebBenzil is a yellow solid and hydrobenzoin is white; therefore, the reduction reaction is evident by the color change. Reduction of an aldehyde or ketone carbonyl group with …
