Arenediazonium o-benzenedisulfonimides (20 examples, yield >90%) were prepared in the dry state by diazotization of aromatic amines with i-pentyl nitrite and o-benzenedisulfonimide in glacial acetic acid or formic acid at 0–5°C. Unlike most diazonium salts in the dry state, these salts are very highly stable.

Abstract
Arenediazonium o-benzenedisulfonimides (20 examples, yield >90%) were prepared in the dry state by diazotization of aromatic amines with i-pentyl nitrite and o-benzenedisulfonimide in glacial acetic acid or formic acid at 0–5°C. Unlike most diazonium salts in the dry state, these salts are very highly stable.
