Deep eutectic solvent as an operative media on structure‐reactivity relationships

Abstract: Deep eutectic solvents seem to be environmentally friendly solvents, particularly because they are prepared easily and have very low‐vapor pressures under ambient conditions. They are suitable candidates as green solvents for reaction media with special properties. To present this behavior, substitution reactions of some para‐ and meta‐substituted anilines with 1‐fluoro‐2,4‐dinitrobenzene have been spectrophotometrically investigated in varying mole fractions of ethaline as a deep eutectic solvent in dimethyl … Show more

“…These {glyceline+DMSO} mixtures, which are stable over the entire composition range for temperatures T ≥ 293.15 K, are of practical interest due to their significantly lower viscosity compared to neat glyceline. Recently, DESs mixed with DMSO have been considered as operative media for substitution reactions of para- and meta-substituted anilines with 1-fluoro-2,4-dinitrobenzene. , The employed DESs were 1:2 ChCl/ethylene glycol, usually called ethaline, , and glyceline . The analysis of the solvent effect on the reaction kinetics showed that the reactants and intermediate products are preferentially solvated by DES components and DMSO, respectively, which can be used as a factor of controlling the reaction rate.…”

“…2 (d, F-C-C 2,4-Dinitrofluorobenzene 1 (200 mg, 1.1 mmol) in EtOH (15 mL) was mixed with aniline (200 mg, 2.2 mmol) for 3 h at room temperature. 25 The precipitate was filtered and air dried to give the title compound (130 mg, 46 %) as orange/ red crystals, m.p. 158-159 °C (from dichloromethane:light petroleum ether).…”

“…Let us start by considering a homologous reaction series that follows either the Hammett or the Taft equation irrespectively of temperature (within a certain range). In the hypothetical case chosen as an example, the reaction constant (slope of the LFER-type plot) is negative (  or *  < 0), corresponding to a favorable effect of the electron-donating substituents [55,56], whereas a positive value (  or *  > 0) would correspond to a favorable effect of the electron-withdrawing substituents [57,58].…”
