Metal-polymer catalysts in the reaction of hydrogenation of benzene have been studied. Salts of nickel, palladium, and H2PtCl6·6H2O were used as metals, which were deposited on polymer carriers, in particular, on polyethylenepolyamine, poly-2-methyl-5-vinylpyridine, styrene copolymer with maleic anhyd¬ride, and poly-4-vinylpyridine. A number of polymer complexes were also synthesized, tuned to benzene hydrogenation products and cross-linked with N,N'-methylenebisacrylamide, a crosslinking agent. The temperature of the hydrogenation reaction was controlled within 20–600C. Hydrogenation was carried out in an autoclave. It has been established that complexes based on platinum and poly-4-vinylpyridine lead to a high yield of the product of incomplete hydrogenation of benzene, cyclohexene. Also, it has been established that the Pt-poly-2-methyl-5-vinylpyridine complex tuned to benzene and cyclohexene exhibits a higher catalytic activity

The focus of the present study is liquid-phase oxidation of alkylaromatic hydrocarbons, particularly that of ethylbenzene, in the presence of cobalt-based polymer complexes tuned to ethylbenzene and obtained based on cobalt salts and a copolymer of diethyl ether of phenylphosphonic acid with acrylic acid. The reaction was carried out without solvent at atmospheric pressure and 900C temperature in a glass temperature-controlled equipped reactor. Oxidation was carried out by bubbling gaseous oxygen through the reaction mass. It is shown that tuning leads to a significant increase in the rate of formation of oxidation products. The heterogeneous-homogeneous mechanism of the process, the formation of radicals on the surface with their subsequent release into the liquid volume and the formation of products based on the radical-chain mechanism have been established. We also studied the specificity of the complexʹs ability to tune to α-phenylethyl hydroperoxide in a way identical to its ability to tune to ethylbenzene. As a result of our study, α-phenylethyl hydroperoxide, methylphenylcarbinol and acetophenone were obtained
