Borirane is a heterocyclic organic compound with the formula C2H4BH. This colourless, flammable gas is the simplest borirane, a three-membered ring consisting of two carbon and one boron atom. It can be viewed as a structural analog of aziridine, with boron replacing the nitrogen atom of aziridine. Borirane is isomeric with ethylideneborane.
This compound has five isomers.
