A mild, practical and efficient strategy to prepare β-keto sulfones has been developed by visible light promoted reactions. This reaction involves Ir(ppy)2(dtbbpy)PF6 catalyzed direct funcationalization of alkenes with sulfonyl chlorides under mild conditions. Air was used as oxidant without any additives. The transformation affords the corresponding products in moderate to high yields.
通过可见光促进的反应,已经开发出一种温和,实用和有效的制备β-酮砜的策略。该反应涉及在温和的条件下,Ir(ppy)2(dtbbpy)PF 6催化的烯烃与磺酰氯的直接官能化反应。空气被用作氧化剂,没有任何添加剂。该转化以中等至高产率提供了相应的产物。
