Título: | Structural characterisation of 2,3-disubstituted pyrazines: NMR and X-ray crystallography |
Autor: | Farrán, M. Ángeles; Claramunt, Rosa M.; López, C.; Pinilla, Elena; Torres, M. R.; Elguero, José CSIC ORCID | Fecha de publicación: | 2005 | Editor: | Elsevier | Citación: | Journal of Molecular Structure 741: 67- 75 (2005) | Resumen: | 2-Formyl-3-aminopyrazine (1), 2-acetyl-3-aminopyrazine (2) and 2-benzoyl-3-aminopyrazine (3) have been studied by multinuclear magnetic resonance spectroscopy in solution and in solid state. Amino-imine tautomerism in such derivatives has been discussed on the basis of the calculated stabilities of the different tautomers by the hybrid B3LYP/6-31G** method. The crystalline structure of compound 3 has been solved, it belongs to the monoclinic P21/n space group, and shows supramolecular architectures involving N-H⋯O and N-H⋯N-pyrazine intermolecular hydrogen bonds. © 2005 Elsevier B.V.
