Aliphatic Nitriles

A simple and convenient approach to the synthesis of symmetrical N,N′-alkylidine bisamides is described. Aromatic and aliphatic nitriles react with aromatic aldehydes in the presence of sulfamic acid to give the corresponding bisamides in moderate yields.Key words: alkylidine bisamides, nitrile, sulfamic acid.
