Selective hydrogenation catalyzed by polymeric palladium and platinum complexes

Abstract

Abstract An organic polymer containing a diphenylbenzyl‐phosphine functional group, combined with PtCl 2 or PdCl 2 , gives a heterogeneous hydrogenation catalyst which is analogous to the homogeneous catalysts PtCl 2 (Pø 3 ) 2 and PdCl 2 (Pø 3 ) 2 . In the hydrogenation of soybean methyl ester, this catalyst is highly selective, the products being monoene and diene, with almost no increase in the content of saturated ester.
