rare example of EDA photochemistry in a catalytic regime. The synthetic utility is demonstrated through visible light-driven radicaltrifluoromethylation and Minisci alkylation reactions. The scalability of the EDA complex-promoted reaction is evidenced by the successful multigram-scale trifluoromethylation of methyl N-Boc pyrrole-2-carboxylate in a continuous flow manifold.

oxidative C-2 arylation followed by sulfonylmigration is described. The simple, easyaccess to the highlyfunctionalized free-NH pyrroles secures opportunities for the preparation of compounds with promising biological activities in contemporary organic synthesis. The event of sulfonylmigration from pyrrole-N to C-3 is thermodynamically favored as revealed by density functional methods. The different plausible
