| | Tetramethylene sulfoxide Usage And Synthesis |
| 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. | | Synthesis Reference(s) | Journal of the American Chemical Society, 63, p. 2939, 1941 DOI: 10.1021/ja01856a021
