Borole is a theoretical heterocyclic organic compound a five-membered ring with the formula C4H4BH. It is classified as a metallole. It can be viewed as an structural analog of pyrrole with boron replacing the nitrogen atom of pyrrole. The unsubstituted compound has not been isolated. Substituted derivatives which have been synthesized are called boroles. Although the Hückel’s rule cannot be strictly applied to borole it is considered to be anti-aromatic.
