Description
Pyridine sulphur trioxide is an important reaction reagent that can react with various compounds such as aldehydes, anthracenes and pyrroles to produce other heterocyclic compounds. Pyridine sulphur trioxide is primarily used in addition reactions or sulphonation processes.
Chemical Properties
white solid
Uses
Usually used for sulfations of alcohols, sulfonations, deoxygenations and other reductions, oxidations with DMSO.
Uses
Pyridine-Sulfur Trioxide Complex is used in the sulfation of squid ink polysaccharides (SIPs) as a potential candidate compound for the prevention of tumor metastasis. Pyridine-Sulfur Trioxide Complex
is also used in the preparation and anticoagulation test of sulfated silk fibroin.
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.
reaction suitability
reagent type: oxidant
Purification Methods
Wash the solid with a little CCl4, then H2O to remove traces of pyridine sulfate, and dry it over P2O5. [Baumgarten Chem Ber 59 1166 1926, Olah et al. Synthesis 59 1979, Beilstein 20/5 V 184].
