Article abstract of DOI:10.1039/DT9820000445

Soluble and divinylbenzene cross-linked (8percent) polystyrene functionalized with 'pd' groups (Hpd=pentane-2,4-dione) interact with M(pd)n (M=Fe, n=3; M=Co, n=2; M=Cu, n=2; M=Zr, n=4), , , TiCl4, Cl2 (en=H2NCH2CH2NH2), and FeCl3 to give polymer-anchored metal complexes.Thermal decarbonylation of polymer-anchored , monitored by i.r. spectroscopy, suggests formation of a partially decarbonylated pd-bridged intermediate followed by Rh-pd bond cleveage.Hydrogenation of cyclohexene at 109 deg C and atmospheric pressure of cyclohexene is catalysed by polymer-supported and .Formation of metal crystallites on the polymer seems to be responsible for the observed catalytic activities.
