A borabenzene is a heteroaromatic compound that has a boron atom instead of the carbon atom of a benzene molecule. A free borabenzene, which has no donor ligand on the boron atom, has not yet been isolated despite its simple structure and the chemical robustness of boron-carbon bonds. The instability of this molecule results from the high Lewis acidity of the boron atom due to its electron deficiency. All attempts to create a free borabenzene have resulted in formations of complexes with anionic or neutral ligands (even a nitrogen molecule can coordinate to a borabenzene). However, the complexes with anionic ligands, called boratabenzenes, show rich chemistry including the coordination chemistry as anionic π-type ligands. Borabenzene is also stable with electron donor molecules such as pyridine or triphenylphosphine.
