An electrochemical reduction of carbonyl compounds, including ketones and aldehydes provides a variety of alcohols or diols as major products with decent yields. This sustainable and practical reaction proceeds smoothly in air at ambient temperatures with DABCO as the sacrificial reductant. The direct electrochemical reduction is either followed by protonation or radical-radical homocoupling.
