Reactions of cyclammonium cations
The π-electron charges, bond orders, energies of the singlet and triplet electronic transitions, and the PMR spectrum of 4,9-diazapyrene were calculated by the self-consistent-field (SCF) method with allowance for the coulombic repulsion, and the results are compared with the experimentally found positions of the long-wave bands in the UV spectrum and the experimental PMR spectrum. 4,9-Diazapyrene hetarylates activated aromatic and heteroaromatic rings.
