The synthesis of PN type phosphine ligands and their Pd (II) complexes, investigation of catalytic activities in Heck and Suzuki reactions

In this thesis, derivative 4-(2-(2-(diphenylphosphino)benzylideneamino)ethyl)phenol and 4-(2-(diphenylphosphino)benzylideneamino)-3-methylphenol) ligands and their Pd(II) complexes with P and N donor atoms were synthesized starting with 2-diphenylphosphino benzaldehyde. The structures of all the synthesized compounds were illuminated with FT-IR, 13C, 1H, 31P NMR and elemental analyzers. The catalytic activities of complexes were tested for the Heck reaction and Suzuki reaction. The reactions were performed under on inert gas atmosphere (N2) using different bases (NEt3, Na2CO3, NaOAc and K2CO3) and organic solvents (toluene, N-methylpyrrolidone, dioxane and dimethylformamide). According to the GC analysis the results show that in both Heck and Suzuki reactions high conversion is achieved and that each one of the synthesized iminophosphine-Pd(II) complexes are good catalysts.
