A Di‐Substituted Boron Dication and Its Hydride‐Induced Transformation to an NHC‐Stabilized Borabenzene

Abstract

Give me a B: A stepwise chloride abstraction of [Cp*BCl2(IMes)] resulted in the linear di-substituted boron dication [Cp*B(IMes)]2+. The hypercoordinated boron dication, stabilized in the pentagonal pyramidal [C5B]2+ cluster, reacts with superhydride to yield the N-heterocyclic carbene-stabilized borabenzene, [C5Me5B(IMes)] (see scheme).
