DUAL REACTIVITIES OF 1,2-DISUBSTITUTED DIHYDRO-N-HETEROAROMATIC SYSTEMS. 3. ELECTROCHEMICAL AROMATIZATION OF SUBSTITUTED N-ACYLDIHYDROPYRIDINES AND IMIDAZOLES

Article abstract of DOI:10.1007/BF00522127

The principal pathway in the fragmentation of the cation radicals of N-acyl-α(γ)-substituted 1,4-dihydropyridines and 1,2-dihydroisoquinolines, as well as 1,2-dihydroimidazoles and 1,2-dihydrobenzimidazoles, that are formed in the electrochemical oxidation of the indicated N-acyldihydro-N-heteroaromatic systems is the loss of a proton and the subsequent loss of another electron or detachment of an N-acyl residue in the form of a cation and subsequent detachment of an electron to give the corresponding γ(α)-substituted heteroaromatic cations.
