Catalyst-free gem-chlorosulfurization of difluoromethyl-substituted diazo compounds with disulfide and PhICl2

A series of gem -chlorosulfurization products bearing difluoromethyl substituents were synthesized from TsCF 2 CHN 2 , disulfides and PhICl 2 under mild conditions, which could be efficiently converted to multi-component products by a facile operation.
