- Abstract
- Abstract The reduction of an N ‐heterocyclic carbene (1,3‐diisopropyl‐4,5‐dimethylimidazolin‐2‐ylidene, I i Pr ) adduct of dichloro( ortho ‐bromophenyl)borane by tert ‐butyl lithium at low temperature yields the I i Pr adduct A of parent benzoborirene, a highly strained boron‐containing bicyclic compound. A is unstable at room temperature and dimerizes at low temperature to the bis‐I i Pr adduct of 9,10‐dihydro‐9,10‐diboraanthracene, characterized by single‐crystal X‐ray crystallography.
