Cesium carbonate-promoted synthesis of aryl methyl sulfides using: S -methylisothiourea sulfate under transition-metal-free conditions

Zhang, Caiyang,Zhou, You,Huang, Jintao,Tu, Canhui,Zhou, Xiaoai,Yin, Guodong

, p. 6316 - 6321 (2018)

In the presence of cesium carbonate, an efficient synthesis of aryl methyl sulfides by the reactions of aryl halides with commercially available S-methylisothiourea sulfate is developed. This odourless and highly crystalline solid can be used as the subst
