Investigation of the complexation behaviour and catalysis of IBiox-[(−)-menthyl]·HOTf
摘要:
Herein we provide an overview on the unique properties of the sterically demanding IBiox-[(-)-menthyl]center dot HOTf ligand (such as flexibility and sterics) and an application of this ligand in Pd-catalyzed asymmetric intra- and intermolecular alpha-arylation reactions. Furthermore we demonstrate the synthesis of novel NHC metal complexes and a new bifunctional NHC ligand whilst insight into the mechanistic mode of action of IBiox-[(-)-menthyl]center dot HOTf in catalysis is provided.
