The enantioselective cathodic reduction of some prochiral ketones viz. acetophenone (I), propiophenone (II), butyrophenone (III), valerophenone (IV), isobutyrophenone (V), and pivalophenone (VI) has been accomplished at a mercurypoolcathode in N,N-dimethylformamide (DMF)–water (90 : 10) using tetrabutylammonium fluoroborate (TBA·BF4) as a supporting electrolyte in the presence of (1R,2S)-(-)-N,N

A sustainable, practical, and direct strategy for the reduction of carbonyl compounds, including aldehydes and ketones, by an electrochemical pathway is presented, affording a variety of alcohols or diols as major products with decent yields. The reaction proceeds smoothly in the air at ambient temperatures with DABCO as the sacrificial reductant. Mechanistic studies revealed that direct electrochemical
