Specs:Purity:98%,Active SO3>48.8%
Sulfur trioxide pyridine complex is a complex formed where the lone pair on the nitrogen of the pyridine binds to the sulfur of the sulfur trioxide. The resulting compound is used as an activating electrophile in a Parikh-Doering oxidation.[1]
The compound strongly violates the octet rule, as sulfur here has 12 or 14 electrons in its valence shells, depending on whether the S-N bond is viewed as dative or not.
