Recent progress in homogeneous supported asymmetric catalysis: example of the BINAP and the BOX ligands

Industrial developments of asymmetric catalysis are slowed down by cost and toxicity of the soluble transition metal complexes which are used as catalysts. This problem could be solved by using homogeneous supported catalysis among other technologies. The article analyzes recent results obtained in the fields of catalysis using transition metal complexes grafted on organic or inorganic materials. Two types of ligand are considered: BINAP and BOX. In these two cases several approaches are still under investigations and some of them appear to give a higher performance, such as the polymer with ligand in the main chain and with rigid spacer in case of the BINAP and the ligand grafted on silica particles in the case of BOX.
