The lightest double bond , that is, the one between two atoms of boron, was finally realized in an electroneutral compound. Robinson et al. satisfied the electron demand of HBBH through coordination of two molecules of an N‐heterocyclic carbene (see scheme). As by‐product, the base‐stabilized parent diborane(4), the formal hydrogenation product of the title compound, was isolated.
