Item type:Publication, How the Nature of an Alpha-Nucleophile Determines a Brønsted Type-Plot and Its Reaction Pathways. An Experimental Study(2022); ;Ricardo A. TapiaCristian Suárez-Rozas<jats:p>The reactions between 2-chloro-5-nitro pyrimidine with a serie of α-nucleophile derivatives were kinetically evaluated. The kinetic study was carried out in aqueous media and the data shown an unusual split on the Brønsted type-plot, opening a controversial discussion based on reactivities and possible reaction pathways. These split Brønsted type-plots are discussed over the hypothetical transition state (TS) structures associated to concerted or stepwise mechanisms with emphasis on hydrogen bond interactions between electrophile/nucleophile pair able to determine the reactivities and the plausible reaction routes.</jats:p>15Scopus© Citations 1 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Site activation effects promoted by intramolecular hydrogen bond interactions in SNAr reactions(2014) ;Sebastián Gallardo-Fuentes ;Ricardo A. Tapia ;Renato Contreras<p>The nucleophilic aromatic substitution reaction of benzohydrazide derivatives towards 2-chloro-5-nitropyrimidine is used as model system to experimentally and theoretically show that intramolecular hydrogen-bond formation operates as a perturbation that elicits a dual response at the reaction center of the transition state (TS) structure.</p>1Scopus© Citations 13 - Some of the metrics are blocked by yourconsent settings
