A one‐pot synthesis of functionalized thiopyran derivatives via a Cu‐catalyzed multicomponent reaction of sulfonyl azides, arylacetylenes and dipotassium 2,2‐dicyanoethylene‐1,1‐dithiolate, generated from malononitrile and CS 2 , has been developed. When alkylacetylenes were used as the terminal alkynes, N ‐(alkanethioyl)‐ N ‐(2,2‐dicyanoethanethioyl)methanesulfonamides were obtained in good yields.
