摘要
An efficient catalytic system employing TMS center dot OTf for the regioselective thiolation of electron-rich arenes with sulfonyl hydrazides has been developed. The reaction occurs in a solvent mixture of dichloroethane and trifluoroethanol under mild conditions, with the addition of water. This method furnishes a range of para-thio-substituted arenes and 3-sulfenyl-indoles in good to excellent yields, marking a significant advancement in organic synthesis.
