Libraries of Bidentate Phosphorus Ligands; Synthesis Strategies and Application in Catalysis Eur. J. Inorg. Chem. 192008

The cover picture showsstructures that represent three different ways of making phosphorusbased ligand libraries: modular synthesis, solidphase synthesis and formation of ligands by assembly of smaller building blocks. These ligand libraries are important for the rapid identification of new catalysts for asymmetric conversions. In this Microreview on p. 2939 ff J. N. H. Reek et al. show examples that illustrate these strategies.
