1-Alkyl-1,3-diazapyrenium salts were prepared according to two procedures. Oxidative hydroxylation of these salts afforded 1-alkyl-1,3-diazapyren-2-ones. The spectral characteristics of the resulting compounds are discussed.

Reactions of perimidines and perimidin-2-ones with α,β- unsaturated carbonyl compounds gave various 1,3-diazapyrene derivatives. Acylation of 1-methylperimidine, perimidin-2-one, and 1-methylperi-midin-2-one with cinnamoyl chloride in the presence of AlBr3 is accompanied by peri-fusion at the 6,7-position and dearylation of the intermediate product. Under analogous conditions, 1,3-dimethyl-2,3-dihydroperimidine gave rise to 6-cinnamoyl-1,3-dimethyl-2,3-dihydroperimidine. Reactions of perimidin-2-ones with 1,3-di-phenyl-2-propenone in polyphosphoric acid resulted in peri-fusion at the 6,7-position, and with acetylacetone, at the 1,9-position.
