An efficient method for the selective N-monovinylation of primary aromatic amides using calcium carbide as an alkyne source was described. A series of N-vinylbenzamides (enamides) RC(O)NHCH=CH2 [R = Ph, 2-MeC6H4, 4-ClMeC6H4, etc.] were readily synthesized by this strategy. The salient features for this protocol were the use of inexpensive, easy-to-handle solid alkyne source, high chemoselectivity, transition metal catalyst-free, good functional group tolerance, and simple work-up procedures. These reactions was also be extended to the gram-scale level.
