TL;DR: In this paper, the standard enthalpy of sublimation, at the reference temperature of 298.15 K, was measured by the vacuum drop microcalorimetric technique, using a High Temperature Calvet Microcalorimeter as (182.1 ± 1.7) kJ · mol-1.
Journal ArticleDOI
Double proton transfer in crystals of 1,3,4,6,7,8‐hexahydro‐2H‐pyrimido[1,2‐a] pyrimidine (hppH): 13C and 15N CPMAS NMR study of (hppH)2
Martyn P. Coles,Majid S. Khalaf,Rosa M. Claramunt,M. Ángeles García,Ibon Alkorta,José Elguero +5 more
TL;DR: In this article, a combination of X-ray crystallography, CPMAS NMR (C-13 and N-15) and theoretical calculations is used to determine that a double proton transfer takes place in the (hppH)(2) dimer with an activation energy of about 50 kJ mol(-1).
Journal ArticleDOI
Multinuclear NMR study of Au(I), Pd(II) and Ag(I) pyrazole complexes to investigate the coordination mode
TL;DR: In this article, the coordination effects induced on the 1 H-, 13 C-, and 15 N- NMR chemical shifts of the 3,5-di- (4-butoxyphenyl)-1H-pyrazole, HPzbp2 (1) have been quantified for the following complexes.
Journal ArticleDOI
Proton transfer in rubazoic acid derivatives in solution and in the solid state. An NMR study
TL;DR: In this article, the same authors reported a fast proton transfer equilibrium between two enolic tautomers both in solution and in the solid state for rubazoic acid derivatives.
Journal ArticleDOI
The structure in the solid state and in solution of 3(5)-trifluoromethyl-4, 5(3)-polymethylenepyrazoles
Marcos A. P. Martins,Nilo Zanatta,Helio G. Bonacorso,Fernanda A. Rosa,Rosa M. Claramunt,Mª Ángeles García,M. Dolores Santa María,José Elguero +7 more
TL;DR: In this paper, the tautomerism of polymethylenepyrazoles bearing at position 3(5) a trifluoromethyl group has been studied by NMR in solution (1 H, 13 C, 15 N, 19 F) and in the solid state (13 C,15 N).
