SYNTHESIS AND CATALYTIC PROPERTIES OF ARENE COMPLEXES OF RUTHENIUM(II) PREPARED FROM SI, ZR, TI AND AL ALKOXIDES BY THE SOL-GEL PROCESS

Methods of synthesizing materials for catalysis were developed by synt hesizing eta-arene complexes of ruthenium(II) coordinated to vinylpyri dine that was followed by sol-gel polymerization with 3-methacryloxypr opyltriethoxysilane. To enforce sufficient catalytic properties, a ser ies of hybrid materials from Si, Zr, Ti and Al alkoxides were prepared by co-condensation. The hydrolysis and polycondensation of materials were performed at different experimental conditions. The monomeric com pounds were identified and catalytic activities were tested for cycliz ation of (Z)-3-methylpent-2-en-4-yn-1-ol to 2,3-dimethylfuran.
