A 1H, 13C and 15N NMR study in solution and in the solid state of six N-substituted pyrazoles and indazoles.
TL;DR: The chemical shifts have been compared with GIAO/DFT calculated absolute shieldings and some discrepancies have been analyzed.
Journal ArticleDOI
Synthesis and structural study of 2-arylbenzotriazoles related to Tinuvins
Dolores Santa María,Rosa M. Claramunt,Vladimir Bobosik,M. Carmen Torralba,M. Rosario Torres,Ibon Alkorta,José Elguero +6 more
TL;DR: In this paper, a total number of nineteen 2-arylbenzotriazoles related to the UV absorber Tinuvin P have been studied and some important features related to their behavior discussed on the basis of solution and solid-state NMR, as well as B3LYP/6-311++G(d,p) computational results.
Journal ArticleDOI
Weak Intermolecular CH···N Hydrogen Bonding: Determination of 13CH-15N Hydrogen-Bond Mediated J Couplings by Solid-State NMR Spectroscopy and First-Principles Calculations.

TL;DR: Weak hydrogen bonds are increasingly hypothesised to play key roles in a wide range of chemistry from catalysis to gelation to polymer structure, and here, 15N/13C spin-echo magic-angle spinning (MAS) solid-state NMR experiments are applied to "view" intermolecular CH···N hydrogen bonding in two selectively labelled organic compounds.
Journal ArticleDOI
The Use of NMR Spectroscopy to Study Tautomerism
Journal ArticleDOI
Reactivity of azoles towards benzaldehyde and its dimethylacetal. Synthesis of N,N'-diazolylphenylmethanes
TL;DR: In this paper, 1,1'-diindazolylphenylmethanes have been prepared from indazoles and benzaldehyde in presence of zinc chloride as catalyst, which is strongly dependent on the basic pK a's of azoles and only few pyrazolyl derivatives could be prepared by this procedure.
