Diaryliodonium salts play an increasingly important role as an aryl source. Reported is the first synthesis of diaryliodoniums by rhodium(III)‐catalyzed CH hyperiodination of electron‐poor arenes under chelation assistance. This CI coupling reaction occurred at room temperature with high regio‐selectivity and functional‐group compatibility. Subsequent diversified nucleophilic functionalization of
二芳基碘鎓盐作为芳基源发挥着越来越重要的作用。报道是由铑diaryliodoniums的第一合成(III)催化Ç 轰下螯合援助贫电子芳烃的hyperiodination。这种CI偶联反应在室温下具有较高的区域选择性和官能团相容性。随后对二芳基碘的多样化亲核官能化使得可以容易地构建CC,CN,CO,CS,CP和CBr键,并且在所有情况下,初始功能化均发生在含有螯合剂的芳烃上-团体。
