Above 1300 K, P₂ is “expulsed” in a highly selective fashion from the closo‐diphosphahexaborane 1. This was shown by PE‐spectroscopic investigation of the pyrolysis of 1 under nearly unimolecular conditions. According to approximative calculations of MNDO energy hypersurfaces, the activation proceeds along a narrow potential over a high‐lying saddle point, which qualitatively explains the experimental results.
