Catalytic properties of polyvinylpyridine complexes of palladium

Determination of the loading and stability of Pd in an arborescent copolymer in ethanol by microplasma-optical emission spectrometry

“…Bekturov et al suggested a model for the complexation of PdCl 2 by P2VP which accounts for a 1 : 1 molar ratio of 2VP units and Pd. 7 However, more recently Fernandez et al reported that up to 1/3 of the Pd in commercial Pd(OAc) 2 could be in the form of Pd(0). These reduced species accounted for an excess of Pd measured in polymer brushes decorated with dipyridylamine ligands, when compared to the stoichiometric complexation expected with Pd(II) species.…”

“…Hirai et al showed that alcohols could serve as reducing agents, 5 and that in the presence of a polymeric stabilizer Pd NPs could be prepared. 6 Using a similar strategy, poly(2-vinylpyridine) (P2VP) in the form of linear homopolymers, [7][8][9][10] block copolymers, [11][12][13] and nanospheres 14 was shown to complex with palladium species, even at high temperatures and pressures, 15 and to lead to the formation of Pd NPs aer reduction of the metallic species.…”
