Photoredox-Catalysis\nFluorosulfonyldifluoromethylation\nof Unactivated Alkenes and (Hetero)arenes with ICF<sub>2</sub>SO<sub>2</sub>F

The fluorosulfonyldifluoromethylation of unactivated\nalkenes and\n(hetero)arenes with iododifluoromethanesulfonyl fluoride (ICF<sub>2</sub>SO<sub>2</sub>F) under visible light photoredox catalysis\nwas successfully developed. Key to the successful fluorosulfonyldifluoromethylation\nof aromatic compounds was the usage of AgOTf as an additive to promote\nthe formation of the CF<sub>2</sub>SO<sub>2</sub>F radical. The protocol\nprovided a straightforward way to introduce the interesting and useful\nCF<sub>2</sub>SO<sub>2</sub>F group on sp<sup>3</sup> and sp<sup>2</sup> carbons.
