Preparation of NHC Borane Complexes by Lewis Base Exchange with Amine− and Phosphine−Boranes

Preparation of NHC Borane Complexes by Lewis Base Exchange with Amine− and Phosphine−Boranes

A versatile new method for the preparation of NHC boranes starting from two stable, readily available reactants―an heterocyclic salt and an amine or phosphine−borane―is reported. It uses a Lewis base exchange at boron and provides easy access to new NHC boranes, in particular B-substituted borane on...

Zusammenfassung:A versatile new method for the preparation of NHC boranes starting from two stable, readily available reactants―an heterocyclic salt and an amine or phosphine−borane―is reported. It uses a Lewis base exchange at boron and provides easy access to new NHC boranes, in particular B-substituted borane ones.
