Tetramethylene sulfoxide Chemical Properties, Uses, Production
Chemical Properties
clear colorless to yellow liquid
Uses
In a comparative study of aromatic fluorodenitration with Potassium fluoride, in several dipolar aprotic solvents, a much faster reaction rate was observed with DMSO or tetramethylene sulfoxide than with the more commonly used Sulfolane.
Definition
ChEBI: Tetrahydrothiophene 1-oxide is a member of tetrahydrothiophenes.
