Solvent effect on a model SNAr reaction in ionic liquid/water mixtures at different compositions

2018 , Bruno Sánchez , Cristian Calderón , Constanza Garrido , Renato Contreras , CAMPODONICO GALDAMES, PAOLA ROSSANA

A biphasic behavior observed on the reaction rate of a model SNAr reaction in ionic liquid/water mixtures was explained by preferential solvation effects in water rich mixtures, and an anion effect in mixtures with high ionic liquid content.

Gutmann’s Donor and Acceptor Numbers for Ionic Liquids and Deep Eutectic Solvents

2022 , Bruno Sanchez , CAMPODONICO GALDAMES, PAOLA ROSSANA , Renato Contreras

An experimental and computational methodology for the analysis of the Lewis acid/base responses of ionic liquids (ILs) and deep eutectic solvents (DES) is proposed. It is based on the donor and acceptor of the electronic charge ability of Lewis acid and bases concepts (donicity and acceptor numbers, DN and AN, respectively) proposed by Viktor Gutmann. The binding enthalpy between the IL/DES with the probe antimony pentachloride (SbCl5) in dichloroethane displays good correlations with experimental data. This approach could serve as a first approximation to predict the responses to H-bonding abilities of new IL or DES. Although useful, the problems encountered to model the electron AN of these solvents limit the usefulness of the approach to completely describe their polarity properties. The experimental data were recorded using UV–Vis spectroscopy for a wide range of ILs and a couple of DES. Two reactions were used as benchmarks to test the reliability of the DN model to discuss the reactivity of real systems in these neoteric solvents.

Changes in the SNAr reaction mechanism brought about by preferential solvation

2015 , Jazmín Alarcón-Espósito , Ricardo A. Tapia , Renato Contreras , CAMPODONICO GALDAMES, PAOLA ROSSANA

For model SNAr reactions in mixtures of acetonitrile and water, we found preferential solvation in favor of the aqueous phase.
