Investigation of the catalytic activity of metal complexes fixed on a solid support. 10. Selective hydrogenation of allylbenzene in the presence of heterogeneous Pt-Sn-citrate complexes

New heterogeneous catalysts based on the complexes of platinum with tin(II) citrate were prepared. The catalysts exhibit high selectivity in the hydrogenation of allylbenzene to propylbenzene without increasing the rate of isomerization of the C=C bond. The activity of the complexes depends on the conditions and decreases with increase in the Sn:Pt ratio.N. D. Zelinskii Institute of Organic Chemistry, Russian Academy of Sciences, 117913 Moscow.
