Abstract This study developed a novel strategy based on visible‐light photocatalysis for the construction of 3‐chlorobenzo[ b ]thiophenes. The photocatalytic system exhibits multiple advantages, including mild reaction conditions, cascade reaction, and good tolerance. Mechanistic studies have demonstrated that the chlorine radicals, generated from polychloromethanes, are the key to initiating the tandem reaction.
