Visible-Light-Promoted Activation of Unactivated C(sp3)–H Bonds and Their Selective Trifluoromethylthiolation - Journal of the American Chemical Society (ACS Publications)

Visible-Light-Promoted Activation of Unactivated C(sp3)–H Bonds and Their Selective Trifluoromethylthiolation - Journal of the American Chemical Society (ACS Publications)
Selective functionalization of ubiquitous C(sp3)–H bonds using visible light is a highly challenging yet desirable goal in organic synthesis. The development of such processes relies on both rational design and serendipitous discoveries from innovative tools such as screening technologies. Applying a mechanism-based screening strategy, we herein report photoredox-mediated hydrogen atom transfer catalysis for the selective activation of otherwise unactivated C(sp3)–H bonds, followed by their trifluoromethylthiolation, which has high potential as a late-stage functionalization tool.
