摘要：

This paper describes the first systematic study of the catalytic activity of palladium, ruthenium and osmium 2,3,7,8,12,13,17,18-octaethylporphyrinates heterogenized on silica gel in the reactions of liquid-phase hydrogenation of organic compounds. Parameters of the catalytic activity of the studied porphyrin/silica gel systems in the reduction of substances containing nitro group and double bond were obtained. The possibility to adjust the activity and selectivity of the hydrogenation reactions catalysts based on porphyrin complexes by varying the nature of central metal cation and mass ratio of the impregnated complex was shown. The dependence of reduction selectivity on the presence of substituents in the organic substrate was established for nitrobenzenes.
