摘要：In addition to the previous finding that aliphatic amines reacted with the nitrite ion to form a cyanide ion, aromatic amines, such as p-nitroaniline, aniline, p-toluidine, and ethyl p-aminobenzoate, also reacted with the nitrite ion to form a cyanide ion, the concentration of which was markedly higher than that from the reaction with aliphatic amines. The formation of a cyanide ion from aromatic amines suggests the cleavage of the benzene ring by the nitrite ion.
