The main aim of this dissertation is the synthesis of defined, catalytically active complexes of palladium with fluorescent carbenes, based on quinoline fluorophore. In result of the syntheses, 73 new compounds were isolated, including 33 palladium complexes. They were examined by UV / VIS spectroscopic techniques. Their catalytic properties were tested in a Suzuki model reaction under various conditions. Some of the complexes demonstrated high catalytic activity. Behavior of series of palladium allyl complexes in solution was studied by NMR techniques. Two forms were observed in solutions of the complexes. By capturing of free imidazoquinolinylidene were synthesized several selenoureas which were analyzed by 77Se NMR spectroscopy . The π-acceptor ability of the newly synthesized ligands was studied. |
