Autoxidation of the phosphonatecarbanions derived from 9-phosphono-10-hydroacridanes provided chemiluminescence ascribed to the excited acridone anion. The intramolecular CIEEL (chemically initiated electron exchange luminescence) mechanism can be applied to this chemiluminescence because of the much higher emission efficiency compared to that of 9-phosphono-10-methylacridanes. The effect of the phosphonate

Reactivity of dihydroacridines bearing a С–X fragment at the geminal C-9 atom (where X = C, N, O, P, S) on anode has been investigated by means of electrochemical oxidation and thermodynamic and quantum-chemical calculations. The electrochemical oxidation results either in the formation of the 9-substituted acridines or in the cleavage of the C–X bond. This dual behavior of dihydroazines is analogous
