Arenediazonium o-benzenedisulfonimides were reacted with tetramethyltin, tetrabutyltin or trialkylboranes. The reactions, carried out in the presence of palladium(II) derivatives as precatalysts, gave the methylation and alkylation products with good overall conversions. The o-benzenedisulfonimide was recovered in high yield from all the reactions and could be recycled for the preparation of other salts.

Abstract
Arenediazonium o-benzenedisulfonimides were reacted with tetramethyltin, tetrabutyltin or trialkylboranes. The reactions, carried out in the presence of palladium(II) derivatives as precatalysts, gave the methylation and alkylation products with good overall conversions. The o-benzenedisulfonimide was recovered in high yield from all the reactions and could be recycled for the preparation of other salts.
