The invention relates to the combinatorial approaches to the preparation of novel polymer-supported heteroatom bidentate (PN, PO, PS) ligand libraries and the corresponding free compounds after cleavage from the supports. These compounds are useful as novel ligands in the preparation of metal-containing catalysts.

edifices. Once the PNN ligands were coordinated to platinum, the resulting complexes proved to be very effective as catalysts in a domino reaction, where a Pt-catalyzed reduction of nitrobenzene was followed by a Paal–Knorr pyrrole reaction. In the nitrobenzene reduction, the modified CDs acted both as first- and second-sphere ligands. Contrary to an acyclic glucopyranose-based NN ligand unable to interact
