A transition metal‐free protocol has been developed for the oxidative coupling of primary amines to imines and azobenzenes, thiols to disulfides, and 2‐aminothiophenols to benzothiazoles, offering excellent yields. The advantageous features of the present environmentally benign methodology include the usage of biocompatable and green reaction conditions such as solvent, room temperature reactions,
已开发出一种无过渡金属的方案,用于伯胺与亚胺和偶氮苯的氧化偶联,巯基与二硫化物的氧化偶联以及2-氨基硫酚与苯并噻唑的氧化偶联,具有优异的收率。当前环境友好方法的优势包括使用可生物相容的绿色反应条件,例如溶剂,室温反应,无过渡金属的方法。此外,它提供了更广阔的基板范围。
