Visible-light-promoted photoredox synthesis of thioacetylenes by dehydrogenation coupling of thiophenols and alkynes.

ABSTRACT: Herein, by applying visible-light photoredox catalysis, we achieved the first example of catalytic dehydrogenative coupling of thiophenols and alkynes for the synthesis of thioacetylenes at room temperature under mild reaction conditions. The advantages of our catalytic system mainly lie in the use of air instead of atmospheric oxygen with photoredox catalysis at room temperature.
