A new heterocyclic framework, the dianionic 9,11-diboratacarbazole, has been prepared from a bis-(trimethylphosphine)-stabilized 2,2′ -diborabiphenyl derivative, 1, and H2NR (R = Ph., CH 2C6H4-p-OMe). The heterocyclic framework is formally assembled via Lewis acid chelation of the [NR]2- dianion by 2,2′ -diborabi-phenyl. These dianions are isoelectronic with the well-studied fluorenyl monoanion.
