Investigation of the effectiveness of the new single distributed heterogeneous palladium nanoparticles in the various reactions

In order to be preferred both in the industry and in research laboratories, the catalyst should have properties such as high activity being cheap, easy to remove from the reaction medium, and reusable. In accordance with this purpose, studies on nanoparticle heterogeneous catalyst have been accelerated in recent years. Heterogeneous hydrogenation with H2 and Pd catalysts is one of the oldest and still most important Pd-catalyzed processes in organic synthesis. It maintains its value as a valuable transformation in a wide variety of industries. On the other hand, since the 1960s, coupling reactions are of great importance for organic synthesis. In the meantime the developed reactions named the Kumada, Stille, Sonagashira, Heck, Suzuki, Negishi coupling reactions have an important place. The use of each of these reactions in various areas is increasing day by day. In this study, the catalytic activity of new monodisperse heterogeneous palladium nanoparticles in various reactions were investigated. Firstly, optimised reaction conditions for the hydrogenation reaction with the catalyst were determined. Hydrogenation was carried out various multicomponent molecules. In addition, necessary experiments were conducted for repeated use. Heck and Suzuki coupling reactions have been tested.
