Chiral aryl-substituted motifs are not only prevalent in natural products and pharmaceuticals, but they are also versatile synthons and are present in catalysts/ligands, such as chiral 1,1-diarylalkanes, 1 benzylic alkynes, 2 and axially chiral allenes (Figure ). As demonstrated by chiral 1,1-diarylalkane-based drugs, the subtle variation in the (hetero)aryl pharmacophore can often lead to variations in biological activity. Consequently, the development of efficient and practical catalytic strategies to streamline the installation of different aryl and heteroaryl motifs is an important endeavour for academic and industrial applications. Transitionmetal-catalyzed asymmetric arylations based on an ionic mechanistic pathway currently provide the most robust method for introducing an aryl-or heteroaryl-group into a specific substrate.
