Aminosulfonylation of Arenes, Sulfur Dioxide, and Hydrazines Cocatalyzed by Gold(III) Chloride and Palladium Acetate

N-Amino-sulfonamides can be prepared via a gold(III) and palladium(II) cocatalyzed reaction of arenes, sulfur dioxide, and hydrazines. In the course of the reaction, C-H functionalization and aminosulfonylation processes are involved.
