Pilar Cabildo,Rosa M. Claramunt,Isabelle Forfar,C. Foces‐Foces,Antonio L. Llamas-Saiz,José Elguero +5 more
TL;DR: In this paper, the reaction of NH-pyrazoles with 1 -bromoadamantane in a high pressure stainless steel autoclave gives regioselectively 1-(1 -adamantyl) or 4-(1-adamantsyl) pyrazoles depending on the temperature.
Journal ArticleDOI
Tautomerism of NH-pyrazolinones in the solid state: the case of 3(5)-ethoxycarbonyl-5(3)-hydroxypyrazole
TL;DR: The molecular and crystal structure of the title compound, as determined by X-ray analysis, shows that the tautomeric form present in the solid state is 5-ethoxycarbonyl-3-hydroxypyrazole, 3.5 as discussed by the authors.
Journal ArticleDOI
Solvent effects on the 13C NMR parameters (δ 13C chemical shifts and 1H-13C coupling constants) of 1-methylpyrazole and 1-methylimidazole
TL;DR: In this article, the solvent induced shifts of the three heterocyclic carbons and those of the N -methyl groups are discussed using the Kamiet-Taft-Abboud formalism.
Journal ArticleDOI
The molecular structure of 2-phenylbenzimidazole: A new example of incommensurate modulated intramolecular torsion
TL;DR: In this article, the structure of 2-phenylbenzimidazole, C13H10N2, was solved by charge flipping and refined using the superspace formalism in the (3 þ 1) D superspace group C2/c(0b0) s0 with modulation wavevec-tor q ¼ 0.368b*.
Journal ArticleDOI
Fluorescence spectroscopy and amplified spontaneous emission (ASE) of phenylimidazoles: predicted vibronic coupling along the excited-state intramolecular proton transfer in 2-(2'-hydroxyphenyl)imidazoles.
TL;DR: Methylation at the 1N position of 2-phenylimidazole provides the shortest wavelength for a liquid-state laser dye reported to date and low-temperature absorption spectroscopy confirms aggregation processes for 2-(2'-hydroxyphenyl)imidazoles in solution.
