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.
