Título: | The use of chemical shifts vs. coupling constants for studying tautomerism: A combined experimental and theoretical approach |
Autor: | Sanz, David CSIC; Claramunt, Rosa M.; Alkorta, Ibon CSIC ORCID ; Elguero, José CSIC ORCID | Fecha de publicación: | 2007 | Editor: | Kluwer Academic Publishers | Citación: | Structural Chemistry 18: 703- 708 (2007) | Resumen: | When observing average NMR signals originated from a rapid equilibrium, the procedure to estimate the composition of the mixture is to use interpolation. To illustrate the difficulties of this approach, the much-studied case of the NH and OH tautomers of pyrazolinones will be reexamined. Calculated absolute shieldings and coupling constants were compared with experimental data. Although the large predominance of the OH tautomer in DMSO was confirmed, the result is a little disappointing because no consistency in the percentages was achieved using chemical shifts and coupling constants. © 2007 Springer Science+Business Media, LLC. | Versión del editor: | http://dx.doi.org/10.1007/s11224-007-9208-4 | URI: | http://hdl.handle.net/10261/72476 | DOI: | 10.1007/s11224-007-9208-4 | Identificadores: | doi: 10.1007/s11224-007-9208-4 issn: 1040-0400 e-issn: 1572-9001 |
