Visible-Light-Mediated Synthesis of Trifluoromethylthiolated Arenes

Published as part of the Bürgenstock Special Section 2018 – Future Stars in Organic Chemistry

Abstract

The visible-light-mediated synthesis of trifluoromethylthiolated arenes in the presence of ruthenium-based photocatayst under mild reaction conditions is reported. The trifluoromethylthiolated arenes are obtained using the shelf-stable reagent trifluoromethyl toluenethiosulfonate at room temperature. The reaction proceeds selectively and does not require the presence of any additive. A mechanism is proposed based on the obtained results of EPR as well as luminescence

Key words

visible light - trifluoromethylthiolation - arenediazonium - radical - reaction mechanism
