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
提出了一种通过电化学途径还原羰基化合物(包括醛和酮)的可持续、实用和直接的策略,以良好的收率提供各种醇或二醇作为主要产品。反应在环境温度下在空气中顺利进行,以 DABCO 作为牺牲还原剂。机理研究表明,直接电化学还原,然后是质子化或自由基-自由基同源偶联是主要途径。
