Copper(II) efficiently catalyzes the aerobic oxidation of aryl thioacetamides into the corresponding α-keto aryl thioamides in moderate to high yields in the presence of K2CO3 under O2 atmosphere. This protocol is simple, clean, and generates water as the only byproduct. A mechanism is proposed for the reaction course.
铜(II)在O2气氛下,存在K2CO3的条件下,高效催化芳基硫代乙酰胺的好氧氧化,生成相应的α-酮芳基硫代胺,收率中等到高。本方法简单、干净,并且只生成水作为副产品。对此反应过程提出了一种机制。
