N,N′-bidentate pyridinium amidate (PYA) ruthenium complexes catalyze the selective olefin transfer hydrogenation of α,β-unsaturated ketones in ethanol. Tailoring the aryl substituent enhances the activity and selectivity toward olefin hydrogenation.
Mechanistic investigations about the reaction of Pd–(py-PYA) complexes with two polar vinyl monomers point out the crucial role played by acetonitrile, the catalyst counterion and the polar monomer in controlling the chain walking process.
Pd-PYA complexes as carbon dioxide reduction catalysts.
Water soluble pincer Pd(II) complexes of pyridinium amidate as NNN-chelating ligands have been reported for anticancer activity against breast cancer cell lines.
Palladium complexes with symmetric N,N-bidentate bis(pyridinium amidate) ligands catalyze the olefin polymerization already at mild conditions, when the pyridinium site is ortho,ortho-dimethylated. The carbonyl groups engage in metal coordination.
