describes the development of Rh-catalyzed [2,3]-sigmatropicrearrangement of alkynyl carbenes with allyl sulfides. The protocol exhibits equitable functional group tolerance and allows the formation of a variety of synthetically valuable sulfide-substituted 1,5-enyne products. To the best of our knowledge, this is the first example of [2,3]-sigmatropicrearrangement of alkynyl carbenes. DFT analysis supports
