摘要
Hydride abstraction from the heterocyclic carbene borane adducts (NHC)BH2C6F5(NHC: IMes or IMe4) gave the B-H containing [(NHC)B(H)C6F5](+)borenium cations. They added carbon monoxide to give the respective [(NHC)B(H)(C6F5)CO](+)boron carbonyl cations. Carbon nucleophiles add to the boron carbonyl to give [B](H) acyls. Hydride reduced the [B]CO cation to hydroxymethylborane derivatives.
