| Title | Electronic Spectra and Photochemical Properties of Acetyldihydroquinolinones  | ||
| Abstract | The absorption and luminescence properties o f 6-acetyl-2,3-dihydro-4(lH)-quinolinone are described and compared to those of the parent 2,3-dihydro-4(lH)-quinolinone. The character of the electronic transitions is determined by PPP quantum chemical calculations. An N-acyl migration leading to the form ation of 6-acetyl-2,3-dihydro-4(lH)-quinolinone takes place upon UV irradiation or heating with polyphosphoric acid o f 1-acetyl-2,3-dihydro-4(lH)-quinolinone. A radical mechanism of the photochemical rearrangem ent is proposed. | ||
