A convenient synthesis of several examples of betaines 3 and 4 is reported.The electronic and molecular structure of the title betaines 3 and 4 is investigated in terms of a single-crystal diffraction X-ray analysis of compound 7, spectroscopic methods, and experimental dipole moment values (12.34-15.34 D).Semiempirical molecular orbital calculations (MNDO and AM1 methods) provide a useful complementary information to the experimental results.

A convenient synthesis of the hitherto unknown methylenepyridinium and methyleneimidazolium azolate inner salts is reported.Their structural characterization on the basis of the spectroscopic 1H and 13C NMR data and experimental dipole moments in the range of 12.34 to 15.34 Debye is discussed.
