摘要
(Chemical Presented) H bonds make the catalyst! A single hydrogen bond between ligands coordinated to a rhodium center is critical for the formation of pure supramolecular catalyst for asymmmetric hydrogenation reactions. The ester group of the amidite ligand (see scheme) also forms a hydrogen bond with the coordinated substrate. Use of the herecomplex afforded the highest enantioselectivity reported to date for the hydrogenation of several ester substrates. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
