Facile metal-free visible-light-mediated chlorotrifluoromethylation of terminal alkenes

摘要

A simple and convenient eosin Y-catalyzed procedure has been developed to effect metal-free, visible-light mediated chlorotrifluoromethylation of terminal alkenes with CF3SO2Cl. Several substrates with terminal alkenes including an aromatic heterocycle reacted smoothly to afford various chlorotrifluoromethylated compounds in good to excellent yields. [GRAPHICS]
