β‐Keto sulfones were obtained in good to excellent yields (73–94 %) directly from unactivated olefins by employing inexpensive sodium arenesulfinate salts as sulfonylating agents and K 2 S 2 O 8 as a radical initiator in open flasks and aqueous media at room temperature under transition‐metal‐free conditions. The reported oxidative sulfonylation protocol is highly practical and environmentally benign, as self‐manifested by the extremely mild reaction conditions.
