Reactions between various benzyl alcohols or tert-butyl alcohol and nitriles were carried out in the presence of catalytic amounts (usually 10-20 mol-%) of o-benzenedisulfonimide as a Brønsted acid catalyst; the reaction conditions were mild and the yields of amides were good. The catalyst

Arene mono-and disulfonyl chlorides have been easily synthesized starting from the corresponding anilines via aqueous oxidative chlorination of S-aryl O-ethyl dithiocarbonates intermediates, aryl methyl sulfides, or from arenethiols.
