An efficient Pd-catalyzed regioselective intramolecular aerobic oxidative dehydrocoupling of BH/CH between -carborane and arenes has been achieved with the construction of a series of five-, six- and seven-membered rings under mild reaction conditions. Control experiments indicate that B-H activation proceeds preferentially over the aryl C-H. These new polyarene-carborane conjugates have potential applications in materials as demonstrated by pyrene fused -carborane that exhibits unique dual-phase emission, intramolecular charge transfer (ICT), and aggregation-induced emission (AIE) properties.
在温和的反应条件下，通过构建一系列五元、六元和七元环，实现了一种高效的钯催化的 - 碳硼烷与芳烃之间的BH/CH区域选择性分子内有氧氧化脱氢偶联反应。对照实验表明，B-H活化比芳基C-H活化更优先进行。这些新型的聚芳烃 - 碳硼烷共轭物在材料方面具有潜在应用，例如芘稠合的 - 碳硼烷表现出独特的双相发射、分子内电荷转移（ICT）和聚集诱导发光（AIE）特性。
