Abstract

Soluble and divinylbenzene cross-linked (8%) 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), [VO(pd)2], [Rh(CO)2(pd)], TiCl4, [Ni(en)2]Cl2(en = H2NCH2CH2NH2), and FeCl3 to give polymer-anchored metal complexes. Thermal decarbonylation of polymer-anchored [Rh(CO)2(pd)], monitored by i.r. spectroscopy, suggests formation of a partially decarbonylated pd-bridged intermediate followed by Rh–pd bond cleavage. Hydrogenation of cyclohexene at 109 °C and atmospheric pressure of cyclohexene is catalysed by polymer-supported [Fe(pd)3] and [Rh(CO)2(pd)]. Formation of metal crystallites on the polymer seems to be responsible for the observed catalytic activities.
