Abstract

A greener and inexpensive electrochemical method has been developed for the oxidation of benzyl alcohols by homogeneous electrolysis. The electrochemical reaction was carried out in an undivided cell equipped with carbon and stainless steel electrodes at room temperature. The homogeneous solution made up of acetonitrile/water containing substrate and ammonium bromide with a catalytic amount of H₂SO₄ as supporting electrolyte. The reaction condition was optimized with various electrochemical experimental parameters and evaluated with various substituted benzyl alcohols to result in excellent yield of aldehydes (>83%).

一种快速有效的均相电解氧化苯甲醇的方法

摘要

已经开发出一种通过均相电解氧化苯甲醇的更环保、更便宜的电化学方法。电化学反应在室温下在配备碳和不锈钢电极的未分隔池中进行。均相溶液由含有底物的乙腈/水和溴化铵和催化量的 H ₂ SO ₄作为支持电解质组成。使用各种电化学实验参数优化反应条件，并用各种取代苯甲醇进行评估，以产生优异的醛收率（> 83%）。
