A practical and recyclable electro-oxidation of alcohols to aldehydes and ketones by using -hydroxyphthalimide (NHPI) as the catalyst is presented. Through an undivided pool, under constant current conditions, various alcohols can be oxidized to the corresponding aldehydes or ketones in a high yield. Compared with previous methods, this system has the following characteristics: (1) the catalyst, electrode, electrolyte, and solvent (mainly water) are recyclable; (2) it has many advantages such as mild reaction conditions, easy operation, and good tolerance of functional groups; and (3) it can be smoothly scaled up to kilogram-scale production.
介绍了一种以N-羟基邻苯二甲酰亚胺(NHPI)为催化剂,将醇类实用且可循环的电氧化为醛和酮的方法。通过一个无隔膜电解池,在恒流条件下,各种醇类可以高产率地氧化为相应的醛或酮。与以前的方法相比,该体系具有以下特点:(1)催化剂、电极、电解质和溶剂(主要是水)可循环使用;(2)具有反应条件温和、操作简便、对官能团耐受性好等诸多优点;(3)可以顺利放大到千克级生产。
