We developed hydroxysulfurization and alkoxysulfurization of styrenes using a visible-light synthetic strategy in the absence of photocatalyst and oxidant. This strategy provided the corresponding β-hydroxysulfides and β-alkoxysulfides in moderate to good yields with high regioselectivity. The reaction was tolerated by a wide range of functional groups. This is the first example of ArSSAr/CBr4 system has been introduced into organic transformation. (Figure presented.).

A light-promoted and tertiary-amine-assisted strategy for efficient hydroxysulfenylation of both electron-rich and electron-deficient alkenes with thiophenols to selectively and directly access β-hydroxysulfides in one pot is described herein. In contrast to the previously reported thiol-oxygen co-oxidation reactions, this simple and sustainable approach features mild reaction conditions, high efficiency, and excellent functional group tolerance.

We have developed a highly efficient synthetic route to β-ketosulfones via AgNO3 catalyzed oxysulfonylation of alkenes using thiophenols in the presence of air (O2) and K2S2O8 as eco-friendly oxidants. Thiophenols have been used as sulfonylation precursors for the first time in a dioxygen activation based radical process. Moreover, the protocol also offers a new and convenient method for the synthesis of β-hydroxysulfides at room temperature without the use of any initiator. This journal is
