A THEORETICAL-STUDY OF SOLVENT A Theoretical-Study Of Solvent Effects on The Relative Thermodynamic Stabilities of The Allyl+/F- and Allyl-/Li+ Ion-Pairs in Polar Media
(Elsevier, 1990)
The relative thermodynamic stabilities of several ion-pair structures, including intimate and
solvent-separated forms, in solution have been studied for the allyl +/F- and allyl- /Li + model
systems. The electrostatic ...
Solvent effects on the sensitized photoxygenation of lidocaine
(Elsevier, 2001)
Detection of O2(1Δg) phosphorescence emission, λmax=1270nm, following laser excitation and steady state methods were employed to determine both the total constant, kT LID, and the chemical reaction rate constants, kR LID, ...
Quantum mechanical and molecular dynamic approaches to describe solvation effects by neoteric solvents
(Elsevier, 2020)
This review deals with the problem of designing safer solvents for chemical transformation and chemical processes. These materials generically defined as neoteric solvents include the well known ionic liquids (ILs) and ...
Synthesis of 1,5-benzodiazepines with unusual substitution pattern from chalcones under solvent-free microwave irradiation conditions
(2009)
1,5-Benzodiazepines have been synthesized from the corresponding 2'-hydroxychalcones [1-(2-hydroxyphenyl)-3-aryl-2-propen-1-ones] and o-phenylenediamine, both in methanol, under reflux and under solvent-free microwave ...
Solvent effects on reactions of singlet molecular oxygen, O2(1Δg), with antimalarial drugs
(2004)
Detection of O2(1Δg) emission, λmax=1270 nm, following laser excitation and steady-state methods were employed to measure total reaction rate constants, k T, for the reaction between singlet oxygen and the antimalarial ...
Solvent effects on the amidic bond. 1H nuclear magnetic resonance study of acetamide and N-methylacetamide
(1981)
The influence of various common basic solvents on the 1H n.m.r. spectra of the N-H protons in N-methylacetamide and acetamide has been studied. The chemical shifts at infinite dilution show approximately linear relationships ...
Application of switchable hydrophobicity solvents for extraction of emerging contaminants in wastewater samples
(MDPI, 2020)
In the present work, the effectiveness of switchable hydrophobicity solvents (SHSs) as extraction solvent (N,N-Dimethylcyclohexylamine (DMCA), N,N-Diethylethanamine (TEA), and N,N-Benzyldimethylamine (DMBA)) for a variety ...
Gutmann's Donor Numbers Correctly Assess the Effect of the Solvent on the Kinetics of SNAr Reactions in Ionic Liquids
(2016)
We report an experimental study on the effect of solvents on the model SNAr reaction between 1-chloro-2,4dinitrobenzene and morpholine in a series of pure ionic liquids (IL). A significant catalytic effect is observed with ...
Solvent effect on a model S N Ar reaction in ionic liquid/water mixtures at different compositions
(The Royal Society of Chemistry, 2018)
The reaction of phenyl 2,4,6-trinitrophenyl ether and piperidine was kinetically evaluated in BMIMBF4/water mixtures as the reaction media. This study shows the dramatic effect of the mixture composition on the reacting ...
Cyclic voltammetry and electron paramagnetic resonance study of the electrochemical reduction of p-nitrobenzyl bromidel in aprotic solvents
(1993)
EPR has been used to investigate the radicals postulated as intermediates in the intramolecular electron transfer and dehalogenation of p-nitrobenzyl bromide (p-NBBr) in DMSO and DMFA at room temperature. The electrochemical ...
