N-Imidazolylation of Sulfoximines from N-Cyano Sulfoximines, 1-Alkynes, and N-Sulfonyl Azides

The rhodium-catalyzed N-imidazolylation of N-sulfonyl-1,2,3-triazoles with a variety of N-cyano sulfoximines has been developed for the synthesis of N-imidazolyl sulfoximines via elimination of molecular nitrogen. Copper-catalyzed [3+2] cycloaddition followed by rhodium-catalyzed N-imidazolylation from 1-alkynes, N-sulfonyl azides, and N-cyano sulfoximines is also demonstrated for the synthesis of N-imidazolyl sulfoximines in a one-pot procedure.

Copper-mediated methylthiolation of aryl halides with DMSO

A copper-mediated methylthiolation of aryl halides with the widely available DMSO is described. The procedure tolerates a series of functional groups such as methoxy, nitro, chloro, fluoro, trifluoromethyl, formyl and methoxycarbonyl groups. Thus, it represents a simple and facile methylthiolation procedure.
