Homogeneous catalysis has been widely applied in catalyzed synthesis of organic compounds in chemical industries due to its advantages of mild reaction conditions, high catalytic activity and selectivity. The research goal of this project is the establishment and development of several environment friendly homogeneous catalysis systems for selective synthesis of oxygenated organic compounds. 1. Carbonylation is a significant catalytic process for catalyzed synthesis of the most basic oxygenated compounds in organic chemicals. Lay emphasis of development on design, synthesis and determination of physicochemical properties of ionic liquids bearing catalytic activity. Build up new-type and high efficiency carbonylation systems using carbon monoxide, carbon dioxide, formaldehyde etc. Design, synthesis and characterization of new-type chiral ligands and chiral metallic complexes, studies on structure-activity relationship in asymmetric carbonylation. 2.Selective oxidation of hydrocarbons to oxygenated compounds by molecular oxygen can be realized under mild conditions by biomimetic catalytic oxidation. Develop the cleaner catalytic oxidation system using hydrogen peroxide or molecular oxygen as oxidants, investigate the catalytic cyclic process and the activation mechanism of molecular oxygen and substrates. Build a high efficiency asymmetric oxidation system catalyzed by chiral porphyrin-resembling metal complexes. 3. Biocatalysis is a reaction process which is compatible with the green chemistry. Screening and breeding of strains of methane-utilizing bacteria with high conversion efficiency, establishing biocatalytic conversion system of methane for high efficiency synthesis polyhydroxyalkanoates. Researching the enzyme catalyzed ploymerization and asymmetric resolution reactions in low aqueous media or organic phase, establishing the new methods of chemical-biological consecutive reaction.
