A novel charge‐transfer complex triggered sulfonylation of 1,4‐diazabicyclo[2.2.2]octane (DABCO) with mild reaction conditions has been developed. The formation of a charge‐transfer complex between electron‐withdrawing (hetero)aryl sulfonyl chloride and DABCO allows the synthesis of N‐ethylated piperazine sulfonamide in good yields. The reaction has a high functional group tolerance. Spectroscopic
