Summary:
In this PhD thesis was studied the synthesis of bidental ligands of
phosphorus-nitrogen-phosphorus type (P-N-P) was studied along with the
preparation of the corresponding complexes of nickel, palladium and platinum
were prepared. The ligands and the complexes were characterized using infra red
(IR) and nuclear magnetic resonance spectroscopies (NMR), while the molecular
structure in the crystal was analyzed for number of complexes using X-ray
spectroscopy. The complexes that derived from the ligand
(Ph2P)2N(CH2)3Si(OCH3)3 were successfully immobilized on an inorganic carrier
(STx montmorillonite). The aim of the immobilization of the complexes was the
comparison of the catalytic activity between the immobilized complex
(heterogeneous catalysis) and the free complexes (homogeneous catalysis) also
to test the recycling and reuse of the immobilized complex in a series of
catalytic reactions as well. The catalytic activity of the complexes was mainly
studied in C-C bond formation reactions. Nickel complexes were studied for
catalytic activity in Kumada and Suzuki-Miyaura reactions showing satisfactory
results. Palladium complexes exhibited high catalytic activity in
Suzuki-Miyaura cross-coupling reaction for different substrates, showing
catalytic activity at 25 °C. Finaly the catalytic activity of Pt complexes was
tested in catalytic hydrogenation and hydroformylation reactions.
