New diphosphine ligands and their pincer and chelating Pd and Pt complexes

The thesis generally consists of three parts. The first section contains a summary of the studies on phosphorus, phosphines, Platinum and Palladium metals and their general properties, the well-known chelate ligands and their metal complexes, also their catalytic properties. The second section contains experimental works. In the third section, the characterization of synthesized ligands and complexes; the complexes' catalytic studies are shown. Total result for this thesis, we have synthesized and characterizated 3 ligands and 8 metal complexes. Structural properties of the ligands have explained with 31P{1H}-NMR spectroscopy, the complexes (1a, 1a', 1b, 1b', 2a, 2b, 3a, 3a', 3b) structural properties have explained with 31P{1H}-NMR, 1H-NMR, FT-IR. On the other hand, the identity of 3a' and 2a complexes have explained with X-ray analysis, too. 1a, 1a', 2a, 3a' complexes have been employed as catalyst for the Suzuki–Miyaura cross coupling reaction. The best result in the Suzuki–Miyaura cross coupling reaction with complex of 1a' were obtained.
