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

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

Give me a B: A stepwise chloride ion 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 borabenzen...

Zusammenfassung:Give me a B: A stepwise chloride ion 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).
