A 4-tetrafluoropyridinylthio group was suggested as a new photoredox-active moiety. The group could be directly installed on difluorostyrenes in a single step by the thiolene click reaction. It proceeded upon visible light catalysis with 9-phenylacridine providing various difluorinated sulfides as radical precursors. Single electron reduction of the C-S bond with the formation of fluoroalkyl radicals was enabled by the electron-poor azine ring. The intermediate difluorinated sulfides were involved in a series of photoredox reactions with silyl enol ethers, alkenes, nitrones and an alkenyl trifluoroborate. This study involved multiple reactions and reactants, such as 2,3,4,5,6-Perfluoropyridine (cas: 700-16-3Formula: C5F5N).

2,3,4,5,6-Perfluoropyridine (cas: 700-16-3) belongs to pyridine derivatives. Pyridine has a conjugated system of six èŸ?electrons that are delocalized over the ring. The molecule is planar and, thus, follows the H眉ckel criteria for aromatic systems. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Formula: C5F5N
