| | Sulfur Trioxide Pyridine Complex Usage And Synthesis |
| Description | Sulfur trioxide-pyridine complex is a highly reactive compound used for sulfations of alcohols, sulfonations, deoxygenations and other reductions, oxidations with DMSO. | | Uses |
Sulfur trioxide-pyridine complex is used for sulfations of alcohols, sulfonations, deoxygenations and other reductions, oxidations with dimethyl sulfoxide. It is also used as a source of sulfur trioxide especially in the preparation of sulfate esters. Further, it is used as an activating electrophile in a Parikh-Doering oxidation. In addition to this, it is also used in the preparation and anticoagulation test of sulfated silk fibroin.
