Boehm, Stanislav,Ruppertova, Iveta,Havlicek, Vladimir,Kuthan, Josef
, p. 597 - 604 (1996)
Molecular and electronic structure of the titled inner salts 1a-1c is discussed on the basis of the PM3, AM1 and CNDO/2 calculations. Compounds 1a, 1b and 1c were prepared from 1-(benzimidazol-2-yl)-2,6-diphenyl-4-(4-X-phenyl)pyridinium perchlorates (2a-2
OXIDATIVE AND BASIC TRANSFORMATIONS OF SOME 1-HETEROARYLOLIGOPHENYLPYRIDINIUM SALTS. LIMITATIONS TO THE APPLICABILITY OF FERRICYANIDE OXIDATION

Alcalde, Ermitas,Dinares, Immaculada,Elguero, Jose,Fayet, Jean-Pierre,Vertut, Marie-Claire,et al.
, p. 5009 - 5015 (2007/10/02)
Ten mesomeric betaines of the pyridinium azolate class have been prepared from the corresponding pyridinium azole salts.Theoretical calculations (MNDO), experimental dipole moments (10 to 19 D), 1H and 13C NMR spectra, and X-ray structure of pyridinium benzimidazolate inner salts 3 and 17 have been used to determine the electronic and molecular structure of these compounds.
Synthesis of Highly Dipolar Betaines: Pyridinium Azolates
Alcalde, Ermitas,Dinares, Immaculada,Fayet, Jean-Pierre,Vertut, Marie-Claire,Elguero, Jose
, p. 734 - 735 (2007/10/02)
Theoretical calculation have been carried out and experimental dipole moments measured for several pyridinium azolate inner salts; depending on the substituent on the pyridinium ring the compounds are either planar, almost freely rotating molecules, or ar
