Abstract: 2,3-Diaminomaleonitrile (DAMN), a tetramer of hydrogen cyanide, displays weakly basic properties
and has reactivity comparable to o-phenylenediamine. It has emerged as a versatile, cheap as well as a readily
accessible building block towards the synthesis of a variety of organic compounds. The present review focuses
on the applications of 2,3-diaminomaleonitrile for the synthesis of Schiff’s base, imidazoles, pyrazines,
quinoxolines, benzodiazocines, 1,4-diazepines, purines, pyrimidines, pyrazine-tetrazole hybrids, triazoles, thiadiazole,
thiazolidines, porphyrazines, formamidines, 1,3,5-triazepines, pyrrolo[3,4-b][1,4]diazepin-6(3H)-ones,
triaza[22]annulenes, pyrrolo[3,4-f][1,3,5]triazepines, spiro compounds, pyrazoles and 2,3-dicyano-5,7-
bismethylthieno[3,4-b]pyrazine.
