Synthesis, characterization and investigation of catality properties of metal complexes of some new schiffs

Today, environmental pollution is becoming a major threat to all living things on earth. Recently, the use of chemicals has been increasing rapidly in agriculture, cleaning, cosmetics, food, pharmacology and other application areas, especially plastics. Soil and groundwater pollution caused by the use of this chemical triggers environmental destruction. In addition, due to various anthropogenic processes, carbon emissions increase at an astonishing rate and cause global warming, which also leads to unfamiliar natural events (climate change, drought, flood and overheating, etc.). Therefore, considering the demands of the society, it is necessary to develop environmentally friendly methods. For this purpose, 20 years ago, scientists demonstrated the importance of green chemistry and developed an environmentally friendly approach consisting of 12 principles. This approach aims to increase this sensitivity by making the chemical methods used in modern research laboratories environmentally friendly. Although many different methods are used in medicinal chemistry, it is of great environmental and ecological importance to replace these methods with more sensitive and applicable alternatives. For this reason, it is of vital importance to act with this approach in all areas of synthesis, both in Ar-Ge and other research laboratories. In recent years, Schiff bases have attracted the attention of researchers due to their structural properties and have become the most studied ligand in transition metal coordination chemistry. Derivatives of Schiff base and their metal complexes have been widely used in inorganic, biological, analytical chemistry, food industry, paint industry and catalysis. It is thought that this thesis study will be a guide for future research and contribute to the fields of application. The studies carried out within the scope of this thesis can be listed under three dings; 1) Synthesis of Schiff base ligands (L1, L2) and their structural characterization using different spectroscopic methods, 2) Synthesis of Co(II), Pd(II) and Ru(II) metal complexes of L1 and L2 ligands and structural characterization using appropriate spectroscopic methods, 3) Investigation of catalytic activities of Schiff base Pd(II) and Ru(II) metal complexes in Mizoroki-Heck, Suzuki-Miyaura and hydrogen transfer reactions.
