An efficient method for N-vinylation of aromatic sulfonamides usingcalciumcarbide as a concisesolidalkynesource is described. A series of N-vinyl aromatic sulfonamides are easily synthesized by this strategy. Notable features of this protocol are the use of an inexpensive and easy-to-handle solidalkynesource instead of flammable and explosive gaseous acetylene, transition metal-free catalysts
