Photochemical Properties

The absorption and luminescence properties of 6-acetyl-2,3-dihydro-4(1H)-quinolinone are described and compared to those of the parent 2,3-dihydro-4(1H)-quinolinone. The character of the electronic transitions is determined by PPP quantum chemical calculations.An N-acyl migration leading to the formation of 6-acetyl-2,3-dihydro-4(1H)-quinolinone takes place upon UV irradiation or heating with polyphosphoric acid of 1-acetyl-2,3-dihydro-4-(1H)-quinolinone. A radical mechanism of the photochemical rearrangement is proposed.
