A novel, visible‐light‐induced 3‐component synthesis of sulfonylated oxindoles from N ‐arylacrylamides, diaryliodonium salts and sulfur dioxide is described. The reaction provides simple access to a wide variety of 3‐[(arylsulfonyl)methyl]indolin‐2‐ones in moderate to excellent yields under mild conditions at room temperature. The transformation proceeds in the absence of any external photosensitizer and enables an efficient, solely visible‐light‐driven fixation of sulfur dioxide.
