(Pergamon-elsevier Science LtdOxfordInglaterra, 2014)
Síntese e estudo físico-químico de 1,3-imidazóis 2,4,5-trissubstituídos derivados de benzocalcogenazóis
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2016-07-29)
In the following work, an unprecedented series of 2,4,5-trisubstituted 1,3-imidazoles were synthesized from 1,2-diketones and aryl aldehydes, targeting the union of two classes of heterocyclic rings, the imidazoles and ...
Inhibition effects of ionic and non-ionic derivatives of imidazole compounds on hydrogen permeation during carbon steel pickling
(2022-01-01)
Hydrogen embrittlement can occur when atomic hydrogen is absorbed by steel during the acid cleaning process. In the literature, studies of corrosion inhibition by organic compounds in acid solutions have not given attention ...
Generation and Stability of the gem-Diol Forms in Imidazole Derivatives Containing Carbonyl Groups. Solid-State NMR and Single-Crystal X-ray Diffraction Studies
(American Chemical Society, 2018-01)
The stability of gem-diol forms in imidazolecarboxaldehyde isomers was studied by solid-state nuclear magnetic resonance (ss-NMR) combined with single-crystal X-ray diffraction studies. These methodologies also allowed ...
Hexakis(imidazole-N3)nickel(II) oxydiacetate ethanol solvate
(Blackwell Munksgaard, 1999)
The crystal structure of the title complex, [Ni(C3H4N2)6](C4H 4O5)·C2H5OH, is a tightly woven three-dimensional network composed of [Ni(Him)6]2+ cations (Him is imidazole) interlinked by the oxydiacetate anion through six ...
