Investigation of the complexation behaviour and catalysis of IBiox-[(−)-menthyl]·HOTf

Herein we provide an overview on the unique properties of the sterically demanding IBiox-[(−)-menthyl]∙HOTf ligand (such as flexibility and sterics) and an application of this ligand in Pd-catalyzed asymmetric intra- and intermolecular α-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]∙HOTf in catalysis is provided.
