A new electrocatalytic conversion of alcohols to ketones and aldehydes was developed based on an electrochemical study of Shvo's complex. The oxidation of secondary alcohols was efficiently performed under mild conditions using a catalytic amount of Shvo's catalyst, in combination with a sub‐stoichiometric amount of 2,6‐dimethoxy‐1,4‐benzoquinone in N,N‐dimethylformamide at 80 °C. The hydroquinone
基于Shvo配合物的电化学研究,开发了一种新的醇催化电子转化为酮和醛的方法。在温和条件下,使用催化量的Shvo催化剂,在80°C的N,N-二甲基甲酰胺中,与亚化学计量的2,6-二甲氧基-1,4-苯醌组合,有效地进行了仲醇的氧化。由此形成的氢醌借助于电化学装置被连续地再氧化。对于不同的酮,芳族以及脂族和α,β-不饱和酮,均可获得优异的收率。此外,当转化邻位二醇(例如1,2-辛二醇和1,2-癸二醇)时,可以实现对仲醇氧化的化学选择性。
