What is Dimethylsulfonio- and Sulfo-de-hydrogenation on Reaction of Azuleno[2,1,8-ija]azulene (Isopyrene) with the Dimethyl Sulfoxide-sulfur Trioxide Complex as Reagent about?

## Abstract Reaction of azuleno[2,1,8‐ija]azulene (isopyrene, 1) with SO~3~ in the presence of an excess of DMSO leads mainly to mono‐“dimethylsulfonio‐de‐hydrogenation” with formation of 5‐(dimethylsulfonio)isopyrene, the amount of initial sulfonation being relatively small. Subsequently, the 5‐(dimethylsulfonio)isopyrene is relatively slowly sulfo‐de‐hydrogenated to yield 5‐(dimethylsulfonio)isopyrene‐10‐sulfonic acid.
