A facile route to synthesise N-aminosulfonamides through a palladium-catalyzed coupling reaction of aryl nonaflates, sulfur dioxide, and hydrazines is reported. This transformation proceeds in the presence of Pd(OAc)(2)/XantPhos, and TBAB in 1,4-dioxane at 80 degrees C, leading to the corresponding N-aminosulfonamides in moderate to good yields. The reaction scope has been demonstrated, and good functional tolerance is observed. A plausible mechanism is proposed through the insertion of sulfur dioxide.
