ChemInform Abstract: The Chemistry of Nitrilium Salts. Part 4. Some Reactions of 5‐Amino‐4‐(C‐cyanoformimidoyl)imidazoles Obtained from Nitrilium Trifluoromethanesulphonate Salts and Diaminomaleonitrile.

Diaminomaleonitrile (II) reacts readily with the triflates (I) to give mixtures of the isomers (III) and (IV), which, after base treatment under different conditions, afford the imidazoles (V) or (VI).
