Electrochemical approach to the radical anion formation from 2 '-hydroxy chalcone derivatives
(WILEY-V C H VERLAG GMBH, 2006-03)
Three 2'-hydroxy chalcone derivatives were electrochemically reduced to the radical anion by a reversible one-electron transfer followed by a chemical dimerization reaction. Under suitable conditions of the medium, the ...
Reactivity of 1,4-dihydropyridines toward alkyl, alkylperoxyl radicals, and ABTS radical cation
(AMER CHEMICAL SOC, 2003-02)
A series of C4-substituted 1,4-dihydropyridines (DHP) with either secondary or tertiary nitrogen in the dihydropyridine ring were synthesized. All of these compounds together with some commercial DHP derivatives were tested ...
Oxidation of ophthalmic drugs photopromoted by inorganic radicals
(Elsevier Science SA, 2012-09)
The rate constants of the reactions of the sulfate (SO4radical dot−) and hydrogen phosphate (HPO4radical dot−) radicals with the imidazoline derivatives naphazoline, tetrahydrozoline, oxymetazoline, xylometazoline, and the ...
Factorizations of skew braces
(Springer, 2019-09-20)
We introduce strong left ideals of skew braces and prove that they produce non-trivial decomposition of set-theoretic solutions of the Yang–Baxter equation. We study factorization of skew left braces through strong left ...
Synthesis of novel biaryl derivatives of sesamol (5-Benzodioxolol) and evaluation of their antioxidant activity against DPPH radical
(Csiro Publishing, 2013-08)
A simple and direct arylation of sesamol with aryl halides by a photoinduced reaction is reported. Five 6-arylsesamol derivatives were synthesized in order to evaluate possible changes in their antioxidant properties as a ...
Dielectric relaxational behavior of poly(diitaconate)s containing cyclic rings in the side chain
(WILEY, 2003)
Dielectric relaxations of several poly(diitaconate)s with cyclobutyl, cycloheptyl, and cyclooctyl groups in the side chain were investigated. The study was performed by determining the dielectric permittivity and loss, ...
Some remarks about the fusible property of noncommutative polynomial extensions
(Bogotá - Ciencias - Maestría en Ciencias - MatemáticasDepartamento de MatemáticasUniversidad Nacional de Colombia - Sede Bogotá, 2020-05-31)
In this work, we focus on three objectives: first, we investigate fusible property on skew PBW extensions, recognizing conditions that guarantee the property for this family of algebras. Later, we turn our attention to the ...
