title: Copper-catalyzed N-Alkynylations of sulfoximines with bromoacetylenes.
abstract: N-Alkynylated sulfoximines have been obtained by copper-catalyzed cross-coupling reactions starting from NH-sulfoximines and bromoacetylenes in moderate to good yields. The reaction conditions are mild, and the substrate scope is wide.
