An unusual 12‐vertex‐ closo ‐C 2 B 10 /12‐vertex‐ nido ‐C 2 B 10 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.
