Journal ArticleDOI
A theoretical NMR study of polymorphism in crystal structures of azoles and benzazoles
Marta Marin-Luna,Rosa M. Claramunt,Carla I. Nieto,Ibon Alkorta,José Elguero,Felipe Reviriego +5 more
TL;DR: In this paper, the NMR chemical shifts of two azoles and one benzazole whose crystal structures present polymorphism have been computed using the GIPAW approach using 15 N and 13 C nuclei.
Journal ArticleDOI
Synthesis of bis(indazolyl)alkanes from 1-(hydroxyalkyl)indazoles
TL;DR: In this paper, an isomerization process is proposed as a mechanism for this reaction by comparison of these results with those obtained in the presence of p-toluenesulfonic acid and other 1-(hydroxyalkyl)indazoles.
Journal ArticleDOI
Perimidines: a unique π-amphoteric heteroaromatic system
Journal ArticleDOI
2,4-Bisimino-1,3-diazetidines: iminophosphoranes, carbodiimides and related betaines
Pedro Molina,Mateo Alajarin,Carmen López-Leonardo,Felix H. Cano,Antonio L. Llamas-Saiz,Concepción Foces-Foces,Rosa M. Claramunt,José Elguero +7 more
TL;DR: In this paper, the crystal structures of betaines 8d and 8i have been determined and the relationship between the rotation about the [P N]-bond and the hybridization of the nitrogen is perturbated by the intramolecular phenyl-phenyl "stacking type" interaction in 8d, and by steric hindrance of the isopropyl substituent in 8i.
Journal ArticleDOI
Structural characterisation of 2,3-disubstituted pyrazines : NMR and X-ray crystallography
M. Ángeles Farrán,Rosa M. Claramunt,Concepción López,Elena Pinilla,M. Rosario Torres,José Elguero +5 more
TL;DR: In this paper, the 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-N-pyrazine intermolecular hydrogen bonds.
