This is a mild, simple, green and metal-free synthesis method following the traditional method. A variety of thiophenols and mercaptans were investigated under the optimum reaction conditions. It was found that the aromatic ring-supported group could obtain higher yields than the aromatic ring-supported group, and the reaction time was shorter than that of the charged group. At the same time, the substrates of aliphatic and heterocyclic compounds also had higher yields. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书回复修改意见 -->
