The copper-catalyzed trifluoromethylthiolation of pyrroles with a trifluoromethanesulfonyl hypervalent iodonium ylide under mild conditions has been achieved. A broad set of pyrroles could be transformed to the corresponding products in moderate to excellent yields. The reaction mechanism is hypothesized.
