A model reaction of 2-alkyl-3-aminoquinazolones with α-dicarbonyl compounds benzil and its 4, 4′-derivatives, acenaphthenequinone and isatin was studied for the first time. The reaction proceeded in pentafluorophenol and led to the formation of new heterocyclic systems. This approach was used in the synthesis of new thermostable polyheteroarylenes with fluorescent properties, viz., poly(pyridazinoquinazolones).
