1-Acetonyl-3-methyl- and 1-methyl-3-phenacylperimidinium salts react with hydrazine hydrate to give tetrahydro-derivatives of the hitherto unknown heterocyclic system 1,2,4-triazino<4,3-a>perimidine.On boiling in acetic acid with ammonium acetate, 3-phenacyl- and 3-(2',4'-dimethyl)phenacyl-1-methylperidinium salts are converted into 1-methylamino-8-(4-phenylimidazol-1-yl)naphthalenes, with small amounts of 11-methylimidazo<1,2-a>perimidines also being formed.
