The isolation of a stable persistent carbazole-stabilized boron-centered monoradical anion 1˙, which has a high spin density at the B atom, has been reported. It is characterized using the crystal structure and UV-vis absorption spectrum, as well as electron paramagnetic resonance spectroscopy. Interestingly, the B-N bond was activated by the boron-centered radical anion 1˙, which had not been reported before.
