Sažetak
Secondary structures play a key role in facilitating selectivity in supramolecular catalysis.1 In nature, enzymes enable selectivity by having a well-defined tridimensional substrate binding site, supported by non-covalent interactions between amino acids in the backbone. In supramolecular catalysts, amino acids or other oligo-amides can also form well defined secondary structures, mainly by hydrogen bonding but also through other types of weak interactions, thus mimicking the natural active sites of enzymes. In our previous work we have used supramolecular amino acid and diamine ligands in Rh (I) catalyzed enantioselective hydrogenation reactions with very high selectivity.2 Since Rh (I) complexes can be prone to oxidation and problematic to study spectroscopically, we have synthesized and described Pt (II) Pd (II) complexes as model compounds to study these systems. The synthesized Pd (II) complexes are of additional interest as they form different structures than Rh (I) and Pt (II) complexes and can themselves be used as catalysts for different types of reactions such as allylation. In this work we describe the solution structure of Pd (II) complexes by different instrumental methods (1H, 13C, 31P NMR, UV, CD, x-ray, mass spectrometry) as a starting point for their application in enantioselective catalysis.
