Abstract
The anhydro bases formed from 1,2-dialkylquinolinium (I), 1,2-dialkylisoquinolinium (II), and 2,3-dialkylisoquinolinium (III) salts were calculated within the framework of the π-electron approximation of the MO LCAO self-consistent field (SCF) method. It is shown that, in contrast to II and III, I does not undergo recyclization; annelation of the pyridine ring facilitates recyclization. The recyclization indexes are linked with the aromatic character of the pyridine ring and increase as the aromatic character decreases.
