Determining hydrogen-bond strengths in the solid state by NMR: the quantitative measurement of homonuclear J couplings
TL;DR: In this article, the hydrogen bonding strength in the solid state was quantitatively determined by the accurate measurement of 15N−15N J couplings using a straightforward 2D MAS NMR spin-echo approach.
Journal ArticleDOI
Substituent effects on the 15N NMR Parameters of Azoles
Rosa M. Claramunt,Dionisia Sanz,Concepción López,José Antonio Jiménez,María Luisa Jimeno,José Elguero,Alain Fruchier +6 more
TL;DR: In this article, the 15N chemical shifts and coupling constants pertaining to azoles have been gathered from the literature, and the spectra of 14 compounds in several solvents were recorded again and 31 compounds were studied for the first time.
Journal ArticleDOI
Substituent and solvent effects on the proton transfer equilibrium in anils and azo derivatives of naphthol. Multinuclear NMR study and theoretical calculations
TL;DR: In this paper, the tautomeric equilibrium due to proton transfer is compared in a series of anils of 2-hydroxynaphthalene-1-carbaldehyde and azo derivatives of 2naphthol.
Journal ArticleDOI
Study of the reaction of chalcone analogs of dehydroacetic acid and o-aminothiophenol: synthesis and structure of 1,5-benzothiazepines and 1,4-benzothiazines
Om Prakash,Ajay Kumar,Anil Sadana,Richa Prakash,Shiv P. Singh,Rosa M. Claramunt,Dionisia Sanz,Ibon Alkorta,José Elguero +8 more
TL;DR: In this paper, α,β-unsaturated carbonyl compounds, obtained by the reaction of DHA and aromatic (or heteroaromatic) aldehydes, with o -aminothiophenol results in the formation of 1,5-benzothiazepines and/or 1,4-benzinothiazines depending upon the reaction conditions and structure of the aldehyde.
