An efficient and succinct protocol for synthesis of bis(o-carborane) connected by a B–B bond via palladium catalyzed oxidative dehydrogenative coupling cage B–H/B–H bonds was developed the first time. A series bis(o-carborane)s B(4)–B(4)′ B(4)–B(5)′ synthesized with moderate to good yields. This work opens door miscellaneous applications in related disciplines has important value design different kinds biscarboranes.
