“…doi:10.1016/j.reactfunctpolym.2008.09.004 due to the presence of structural units (like-N-, S-, O-heteroatom groups) of polymers. Moreover, polymer network may also exert the influence on the accessibility of reagents to active centers inside the polymer mass [3][4][5]. This latter effect can essentially influence the selectivity of reaction and this effect seems to be especially important in the case of gel-type polymers, exhibiting the ability for swelling in contact with reaction medium.…”

“…Polymer supports have also found significant applications in catalysis [3,4]. Novel porous polymers such as polystyrene divinyl benzene (PSDVB), which has good stability with simple functionalization of organic groups, have been reported [5][6][7][8][9]. Polymer supports associated with nitrogen-containing ligands have been studied because of their stability to oxidation [10].…”

2-(2 0 -Pyridyl)benzimidazole (PBIMH) was functionalized onto chloromethylated polystyrene beads crosslinked with 6.5 % divinylbenzene, and this solid support was then reacted with Na 2 PdCl 4 in methanol. The functionalized beads were then activated using sodium borohydride. The resultant polymer-supported [2-(2 0 -pyridyl)benzimidazole]palladium complex (PSDVB-PBIM-PdCl 2 ) and its activated form were characterized by various physicochemical techniques. XPS studies confirmed the ?2 oxidation state of palladium in the supported complex. The activated complex was found to catalyse the hydrogenation of various organic substrates including olefins, nitro and Schiff base compounds. Kinetic measurements for the hydrogenation of cyclopentene, cyclohexene and cyclooctene were carried out by varying temperature, catalyst and substrate concentration. The energy and entropy of activation were evaluated from the kinetic data. The catalyst showed an excellent recycling efficiency over six cycles without leaching of metal from the polymer support, whereas the unsupported complex was unstable as metal leached out into the solution during the first run.

“…It is well-known that Pd is effective in catalyzing C-C bond formation reactions [27][28][29][30]. Among palladium-catalyzed couplings, the Suzuki-Miyaura [29], Sonogashira [27] and Heck [28] reactions are the most widely used.…”

“…However, there have been few reports on procedures to graft functional polymer chains onto solid supports and the properties, such as catalytic properties, of the shell modified materials. Palladium is a highly active and selective catalyst in C-C bond formation reactions [27][28][29][30]. However, the problem that concerns many researchers is to combine high efficiency of the catalyst with the possibility of its easy separation from the reaction products.…”

Abstract.A reversible addition-fragmentation chain transfer (RAFT) agent with carbazole as Z-group was immobilized on the surfaces of the cross-linked poly (4-vinylbenzyl chloride-co-styrene) (PVBCS) nanospheres with a diameter of about 70 nm by the reaction of benzyl chloride groups in the PVBCS between carbazole and carbon sulfide. Then surface RAFT polymerization of 4-vinylpyridine (4VP) was used to modify the nanospheres to produce a well-defined and covalently tethered P4VP shell. By surface activation in a PdCl2 solution and then reduction by hydrazine hydrate (N2H4·H2O), the P4VP composite shells were obtained containing densely palladium metal nanoparticles. The chemical composition of the nanosphere surfaces at various stages of the surface modification was characterized by X-ray photoelectron spectroscopy (XPS). Transmission electron microscopy (TEM) was used to characterize the morphology of the hybrid nanospheres. The Pd/P4VP shell nanospheres were also applied to the catalytic reaction and proved to be efficient and reusable for the Heck reaction.
