An aerobic, heterogeneously catalyzed oxidative intramolecular coupling reaction of aromatic compounds is reported here. Using commercially available, recyclable heterogeneous metal catalysts, the coupling reactions of o‐terphenyls and 1,ω‐biarylalkanes proceeded quickly under mild conditions, i.e., at room temperature under oxygen as a co‐oxidant almost all within 1 h, to provide the corresponding
在此报道了芳香族化合物的需氧,多相催化的氧化性分子内偶联反应。使用市售的可循环利用的多相金属催化剂,邻-叔苯基与1,ω-联芳基烷烃的偶联反应在温和的条件下迅速进行,即在室温下于氧气下作为助氧化剂在几乎所有的条件下均在1小时内完成,以提供相应的偶联产物,例如苯并菲和苯并菲,收率良好。该反应是一种易于操作,实用且原子经济的偶联方法,在现代有机合成中非常重要。
