Pd-Catalyzed Oxidative Dehydrogenative Cross Coupling of Cage B-H/B-H Bonds at Room Temperature: Synthesis of Bis(o-carborane)s.

Efficient Pd-catalyzed oxidative dehydrogenative cross coupling of B-H/B-H bonds of two pyridyl o-carboranes has been developed, leading to the preparation of B(3)-B(6') heterocoupled and B(3)-B(6') homocoupled biscarboranes with a broad substrate scope at room temperature.
