Treatment of amides from primary amines with strong bases and electrophilic alkenes (acrylonitrile or p-tolyl vinyl sulphone) gives products derived from N-alkylation of the amide. When amides without an N–H bond are used, no reaction occurs unless the amide gives a stabilised carbanion on proton abstraction; C-alkylation then occurs. When N- and C-alkylation can compete, N-alkylation is preferred
