Synthesis and characterization of poly (ionic liquid) derivatives of N -alkyl quaternized poly(4-vinylpyridine)
Gutmann's Donor Numbers Correctly Assess the Effect of the Solvent on the Kinetics of SNAr Reactions in Ionic Liquids
Site activation effects promoted by intramolecular hydrogen bond interactions in SNAr reactions
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.
Activation of Electrophile/Nucleophile Pair by a Nucleophilic and Electrophilic Solvation in a SNAr Reaction
Experimental Analyses Emphasize the Stability of the Meisenheimer Complex in a SNAr Reaction Toward Trends in Reaction Pathways
Effect of the nature of the nucleophile and solvent on an SNAr reaction
The reaction of 2,4-dinitrobenzenesulfonyl chloride toward propylamine was kinetically evaluated in 19 organic solvents and 10 ionic liquids as reaction media.
Specific nucleophile–electrophile interactions in nucleophilic aromatic substitutions
Mechanistic pathways of aromatic nucleophilic substitution in conventional solvents and ionic liquids
Solvation effects on the reaction mechanism for nucleophilic substitution reactions have been kinetically evaluated in conventional solvents and ionic liquids.
Changes in the SNAr reaction mechanism brought about by preferential solvation
For model SNAr reactions in mixtures of acetonitrile and water, we found preferential solvation in favor of the aqueous phase.
