N,N-Disubstitutedcarboxamides containing α-hydrogen atoms undergo self-condensation reaction simply on treatment with Grignard reagents or n-BuLi in THF room temp. The reaction is considerably influenced steric hindrance at the α-carbon and the condensing agent utilized. A possble Claisen-type mechanism is also reported.
