ortho/para-functionalized amine scaffolds from arylhydroxylamines is described. The transformation was featured with new electrophilic trifluoromethylthiolated reagents, good functional group tolerance, and late-stage modification of complex bioactive scaffolds, providing a rapid access to prepare numerous trifluoromethyl- and difluoromethyl-substituted sulfoxides.
