Using 2‐[bis(alkylthio)methylene]‐3‐oxo‐N‐o‐tolylbutanamides 1 as odorless thiol equivalents, an efficient and odorless synthesis of thioethers has been developed. Promoted by NaOH in EtOH, the cleavage of 1 commences to generate thiolate anions, and the generated thiolate anions then react with halides to give various thioethers in good yield. It is noteworthy that only a very faint odor of thiols
使用2- [双(烷硫基)亚甲基] -3-氧代- ñ - ö -tolylbutanamides 1为无臭硫醇当量,硫醚的有效和无臭的合成已经研制成功。在EtOH中由NaOH促进,裂解1开始生成硫醇根阴离子,然后生成的硫醇根阴离子与卤化物反应生成各种硫醚,收率很高。值得注意的是,在反应和后处理过程中都只能感觉到非常微弱的硫醇气味。
