hazardous hydrogen sources and severe environmental pollution in the conventional reduction of aldehydes/ketones to alcohols. We report here a practical, safe, and green electrochemical reduction, which solves these problems to a large extent. Through an undivided cell, Zn(+) and Sn(−) as the electrode, tetrabutylammonium chloride (TBAC) as the electrolyte, water as the solvent and hydrogen source, a wide
传统的醛/酮还原为醇存在一些具有挑战性的问题,例如使用可燃且危险的氢源以及严重的环境污染。我们在这里报道了一种实用、安全、绿色的电化学还原,在很大程度上解决了这些问题。通过一个完整的电池,以Zn(+)和Sn(−)为电极,四丁基氯化铵(TBAC)为电解质,水为溶剂和氢源,多种醛和酮在温和的条件下转化为相应的醇。状况。此外,电解质和水可以循环利用,并且只需使用D 2 O作为溶剂即可实现还原氘化。最后,减少量可以顺利地扩大到公斤级。
