Copper(I) Catalysis at Room Temperature
reported employing diaryliodonium triflates as aryl source using a copper(I) catalyst. The developed protocol is performable at room temperature and easily scalable. The robustness is confirmed with a wide range of substrate studies of both hydantoins and diaryliodonium salts. Sterically complicated ortho‐substituted diaryliodonium salts are also compatible with the reaction protocol.
