Confirmation of an early postulate: B-C-B two-electron-three-center bonding in organo(hydro)boranes

Abstract

Finally, boron did it too: The first example of a dimeric organyl(hydro)borane with a B-B-bridging aryl ring has been elucidated (see picture; B green/blue, C black/gray). It features a B-C-B two-electron-three-center bond and a largely unperturbed aromatic π-electron system.
