three‐component reaction of aryldiazoniumtetrafluoroborates, the 1,4‐diazabicyclo[2.2.2]octane⋅bis(sulfur dioxide) adduct [DABCO⋅(SO2)2] and hydroxylamines under catalyst‐free and additive‐free conditions has been developed, providing aryl O‐aminosulfonates in good yields. Sulfonamides could also be obtained via a one‐pot process through the reaction of aryldiazoniumtetrafluoroborates, DABCO⋅(SO2)2 and amines in
