A method has been developed for the preparation of N-alkynylated sulfoximines involving the copper-catalyzeddecarboxylativecoupling of sulfoximines with aryl propiolic acids. A range of substituents on both the sulfoximidoyl moiety and the aryl group of the propiolic acid were compatible with this reaction process to afford a series of sulfoximidoyl-functionalized alkynes.
