芳烃重氮邻苯二磺酰亚胺与四甲基锡、四丁基锡或三烷基硼烷反应。该反应在钯(II)衍生物作为预催化剂的存在下进行，产生了具有良好总体转化率的甲基化和烷基化产物。从所有反应中以高产率回收邻苯二磺酰亚胺，并且可以循环用于制备其他盐。
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.
