The action of ammonia and primary amines on 1,3-phenalenedione under mild conditions leads to the ready formation of 3-amino-1-phenalenone and its N-alkyl and N-aryl derivatives.Unlike 2-, 5-, and 6-amino-1-phenalenones, 3-amino-1-phenalenone does not form a diazo compound in reaction with sodium nitrite, and this demonstrates its similarity to β-aminovinylcarbonyl compounds.
