Boratabenzene

 ( Boron Heterocycles ) 

Boratabenzene, sometimes called borinate, is the aromatic anion with the formula C₅H₅BH⁻.

Derivatives of boratabenzene are ligands akin to cyclopentadienyl anion. Metallocene of many have been reported. The 1-methyl and 1-phenyl borinates can form some of the few organo-thallium(I) compounds.

Electronically related heterocycles are adducts of the notional borabenzene. The adduct C₅H₅B·pyridine exhibits properties of boratabenzene anion, i.e., it has the character C₅H₅B⁻-N⁺C₅H₅.
