An efficient and succinct protocol for synthesis of bis(-carborane) connected by a B-B bond via palladium catalyzed oxidative dehydrogenative coupling of cage B-H/B-H bonds was developed for the first time. A series of bis(-carborane)s connected by B(4)-B(4)' and B(4)-B(5)' bonds was synthesized with moderate to good yields. This work opens the door for miscellaneous applications of bis(-carborane) in related disciplines and has important value in design and synthesis of different kinds of biscarboranes.
首次开发了一种高效简洁的协议，通过钯催化笼状B-H/B-H键的氧化脱氢偶联反应合成由B-B键连接的双（-碳硼烷）。合成了一系列由B(4)-B(4)'和B(4)-B(5)'键连接的双（-碳硼烷），产率中等至良好。这项工作为双（-碳硼烷）在相关学科中的各种应用打开了大门，在不同种类碳硼烷的设计和合成中具有重要价值。
