首次发展了一种高效、简洁的合成B-B键连接的双邻碳硼烷的方法，即钯催化的笼状B-H/B-H键氧化偶联反应。合成了一系列由B（4）-B（4）′和B（4）-B（5）′键连接的双邻碳硼烷，产率中等至较高。本工作为双邻碳硼烷在相关学科中的广泛应用开辟了道路，对不同类型双碳硼烷的设计和合成具有重要的参考价值。
An efficient and succinct protocol for synthesis of bis(o-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(o-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(o-carborane) in related disciplines and has important value in design and synthesis of different kinds of biscarboranes.
