Give me a B : A stepwise chloride abstraction of [Cp*BCl 2 (IMes)] resulted in the linear di‐substituted boron dication [Cp*B(IMes)] 2+ . The hypercoordinated boron dication, stabilized in the pentagonal pyramidal [C 5 B] 2+ cluster, reacts with superhydride to yield the N‐heterocyclic carbene‐stabilized borabenzene, [C 5 Me 5 B(IMes)] (see scheme).
