the present study, an efficient Cu-catalyzed transthiolation of alkyliodides is developed. Notably, in the presence of CO, thioesters could also be obtained with copper and cobalt as the co-catalyst. This transformation displayed good functional group tolerance and afforded thioesters or sulfides from the corresponding alkyliodides.
在本研究中,开发了一种有效的 Cu 催化烷基碘的转硫醇化。值得注意的是,在 CO 存在下,硫酯也可以用铜和钴作为助催化剂来获得。这种转化表现出良好的官能团耐受性,并从相应的烷基碘中得到硫酯或硫化物。

A new and convenient copper-catalyzed synthesis of alkyl sulfides has been accomplished using S-alkyl butanethioate as a thiol source. This catalytic protocol displayed a good functional groups tolerance and high efficiency. Both secondary and primary alkyliodides can be used in this procedure. In addition, this method features operational simplicity and a wide substrate range, providing a complementary

methylthiotransfer process in organisms, and therefore its functionality is of paramount importance to living organisms. Several methods for the installation of the methylthio group in small molecules have been reported previously; however, procedures starting from unactivated alkenes are rare. Herein, we report a formal hydro/deuteromethylthiolation of alkenes by using dimethyl(methylthio)sulfonium trifluoromethanesulfonate
