A cyclo ‐organoborane with the empirical formula (CR 1 ) 4 (BR 2 ) 4 and not a carbaborane is formed from 1 in the presence of H 2 and Lindlar catalyst. This is due to the use of diisopropylamino groups as substituents R 2 . Compound 2 displays a nonplanar eight‐membered ring and a crystallographically determined twofold axis (R 1 H).
