Synthesis of the First Example of the 12‐Vertex‐closo/12‐Vertex‐nido Biscarborane Cluster by a Metal‐Free B−H Activation at a Phosphorus(III) Center

Abstract:	An unusual 12‐vertex‐closo‐C₂B₁₀/12‐vertex‐nido‐C₂B₁₀ biscarborane cluster was synthesized through an unprecedented regioselective metal‐free B?H activation by a sterically hindered P^III center under mild conditions accompanied by cage‐opening rearrangement. A combination of the electron‐accepting properties of a carborane cage and steric enforcement of close interatomic contacts represent a new synthetic strategy for the activation of strong B?H bonds in carboranes.
