ELECTROCHEMICAL OXIDATIVE AROMATIZATION OF 9-SUBSTITUTED 9,10-DIHYDROACRIDINES: CLEAVAGE OF C–H vs C–X BOND

Abstract

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 to processes reported in literature that take place upon treatment with chemical oxidants.
