N‐polyazolylmethanes. 1. Synthesis and nmr study of N,N′‐diazolylmethanes
Sebastian Juliá,Pilar Sala,José Del Mazo,Manuel Sancho,Carmen Ochoa,José Elguero,Jean-Pierre Fayet,M. C. Vertut +7 more
TL;DR: In this paper, the relative amounts of isomeric mixtures obtained with asymmetric azoles or with equimolar mixtures of azoles are compared with literature results on monoalkylation of azole.

NMR studies in the heterocyclic series. XVIII—Carbon‐13 NMR study of azolium salts. Attempted correlation of chemical shifts with calculated charge densities
TL;DR: In this article, the carbon-13 chemical shifts and the 1J(CH) coupling constants for 18 azolium salts (di-N-methyl-pyrazolium, -indazolium and -benzimidazolate ionides) have been determined and assigned.

The problem of the tautomerism of 4(5)-nitroimidazole: a theoretical and experimental study
Pilar Jiménez,José Laynez,Rosa M. Claramunt,Dionisia Sanz,Jean-Pierre Fayet,M. C. Vertut,Javier Catalán,J. L. G. De Paz,G. Pfister-guillouzo,C. Guimon,Robert Flammang,André Maquestiau,J. Elguero +12 more
TL;DR: In this article, the authors show that in phase gazeuse les deux tautomeres ont des energies comparables tandis qu'en solution le nitomere nitro-4 est beaucoup plus stable than le nitro -5.

Etude de l'équilibre dans les oxazolo[2,3-e], thiazolo[2,3-e] et isoxazolo[2,3-d]tétrazoles. II. Etude de l'effet de la température par dipolemetrie et résonance magnétique nucléaire
Robert Faure,Jean-Pierre Galy,Emile-Jean Vincent,Jean-Pierre Fayet,Pierre Mauret,M. C. Vertut,José Elguero +6 more
TL;DR: In this paper, the equilibrium constant in dioxane between azido and tetrazole isomers has been obtained for five heterocyclic azides (2-azido thiazoles, benzothiazole, benzoxazole, and 3 -azido isoxazoles) by prot...

Synthesis of highly dipolar betaines: pyridinium azolates
TL;DR: Theoretical calculations have been carried out and experimental dipole moments measured for several pyridinium azolate inner salts; depending on the substituent on the pyrinium ring the compounds are either planar, almost freely rotating molecules, or are hindered with the rings perpendicular to each other as mentioned in this paper.
