Jeroen Wassenaar and Joost N. H. Reek identify optimal chiral catalysts for asymmetric hydrogenation.
Take a look at this perspective that gives a brief overview of different classes of phosphine ligands, with a focus on mixed phosphine ligands, incorporating a second coordinating group such as an amine, thiol, phosphite or phosphoramidite.
