Replacement of Less-Preferred Dipolar Aprotic and Ethereal Solvents in Synthetic Organic Chemistry with More Sustainable Alternatives [PDF]

Chemical Reviews, 2022
Dipolar aprotic and ethereal solvents comprise just over 40% of all organic solvents utilized in synthetic organic, medicinal, and process chemistry. Unfortunately, many of the common “go-to” solvents are considered to be “less-preferable” for a number ...

Proton solvation in protic and aprotic solvents

Journal of Computational Chemistry, 2016
Protonation pattern strongly affects the properties of molecular systems. To determine protonation equilibria, proton solvation free energy, which is a central quantity in solution chemistry, needs to be known. In this study, proton affinities (PAs), electrostatic energies of solvation, and pKA values were computed in protic and aprotic solvents.

Anodic oxidation of diphenylsulphoxide in aprotic solvent

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1974
Abstract The voltammetric behaviour of diphenylselenide has been investigated at a platinum electrode in acetonitrile medium. Evidence for three consecutive anodic peaks can be found in linear potential sweep voltammetry; the responses relative both to the second and to the third one are small in height and poorly defined. The processes corresponding

Thermochemistry of Benzene Solution in Alcohols, Aprotic Solvents, and Mixtures of Aprotic Solvents with Methanol

Russian Journal of General Chemistry, 2003
The standard enthalpies of solution of benzene at 25°C in alcohols (methanol, 1-propanol, 1-pentanol, 1-decanol), aprotic solvents (1,4-dioxane, acetone, acetonitrile, dimethyl sulfoxide, dimethylformamide, propylene carbonate), and mixtures of methanol with these aprotic solvents were determined.

Ionizing Power of Aprotic Solvents

European Journal of Organic Chemistry, 2011
AbstractRate constants for the heterolysis reactions (SN1) of a series of chloro‐diarylmethanes in aprotic solvents (dimethyl sulfoxide (DMSO), acetonitrile, carboxamides, etc.) have been determined conductometrically in the presence of amines or triphenylphosphane, which trap the intermediate ion‐pairs and suppress ion recombination.

Perfluoropolymer membrane behaves like a zeolite membrane in dehydration of aprotic solvents

Journal of Membrane Science, 2012
Dehydration of aprotic solvents, frequently needed in pharmaceutical processing, can be implemented easily by vacuum-based pervaporation employing a novel perfluoropolymer-based membrane: perfluoro-2,2-dimethyl-1,1,3-dioxole copolymerized with ...

Sulfolane as a Solvent for Aprotic Electrolytes

ECS Transactions, 2011
Physiochemical and electrochemical properties of sulfolane were tested for potential use as a solvent in lithium batteries. It is considerably less ignitable than solvents used in lithium batteries now. Its higher freezing point can be lowered by additives (Li salts and some other solvents) sufficienty below 0 °C.

Ozonolysis of verbenone in aprotic solvents

Mendeleev Communications, 2009
The ozonolysis of verbenone in methylene chloride and acetonitrile at –60 and 0 °C proceeds with cleavage of the double bond and neighbouring σ-bond to give (1 R ,3 S )-acetyl-2,2-dimethylcyclobutane carboxylic acid. The mechanism of the reaction has been proposed.

Electrochemical reduction of benzenesulphenyl chloride in aprotic solvents

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1978
The cathodic behaviour of benzenesulphenyl chloride has been studied at a platinum electrode in acetonitrile by using cyclic voltammetry and controlled potential electrolysis. It has been evidentiated that PhSCl gives rise, in an one-electron reduction process, to PhSSPh and Cl− according to 2PhSCl+2e−→PhSSPh+2Cl− The chloride ions so generated ...
