Experimental Analyses Emphasize the Stability of the Meisenheimer Complex in a S N Ar Reaction Toward Trends in Reaction Pathways
(2020-07)
The mechanism of SNAr reactions between 2-chloro-5-nitropyrimidine with primary and secondary alicyclic amines, respectively, have been studied by kinetic measurements. The kinetic data obtained in aqueous media opens a ...
Meisenheimer complexes as hidden intermediates in the aza-SNAr mechanism
(Royal Society of Chemistry, 2020)
In this work we report a computational study about the aza-SNAr mechanism in fluorine- and chlorine-containing azines with the aim to unravel the physical factors that determine the reactivity patterns in these heterocycles ...
Photoreactions of n-alkyl-3-nitrophenyl ethers with aromatic amines in SDS micelles: A laser flash photolysis study
(ELSEVIER SCIENCE SA, 2011)
The quenching of the triplet state of three n-alkyl 3-nitrophenyl ethers: 3-nitroanisol (3-NA), n-butyl 3-nitrophenyl ether (3-NB) and n-decyl 3-nitrophenyl ether (3-ND) by four aniline derivatives: aniline (AN), ...
Transformación enzimática del 2, 4, 6-Trinitrotolueno en las cepas T30A y T30B
(2014)
Se estudio la transformación enzimática del TNT en las cepas Stenotrophomonas sp. T30A y Rhizobium sp. T30B. Con este fin, a partir de los extractos de proteínas de las cepas T30A y T30B, se evalúo la actividad TNT-reductasa, ...
Specific nucleophile–electrophile interactions in nucleophilic aromatic substitutions
(Royal Society of Chemistry, 2013)
We herein report results obtained from an integrated experimental and theoretical study on aromatic nucleophilic substitution (S(N)Ar) reactions of a series of amines towards 1-fluoro-2,4-dinitrobenzene in water. Specific ...

Efecto del pH y la temperatura en la degradación del 2, 4,6 Trinitrotolueno, por bacterias aisladas de sitios con presencia de explosivos.
(Universidad de La SabanaMaestría en Diseño y Gestión de ProcesosFacultad de Ingeniería, 2013-06-27)
La fabricación, uso y disponibilidad de explosivos causa problemas sociales y ambientales, por sus características recalcitrantes, mutagénicos y carcinogénicos. En Colombia, la industria militar ha incentivado la búsqueda ...
