rigid cyclopropyl backbone was synthesized and tested in the intermolecularasymmetricHeck reaction. Mechanistic modelling and crystallographic studies were used to predict the optimal ligand structure and helped to design a very efficient and highly selective catalytic system. Employment of the optimized ligands in the asymmetricarylation of cyclic olefins allowed for achieving high enantioselectivities
