Abstract: The functional resin poly-MTEMA–DMAA–MBA (MTEMA, 2-(methylthio)ethylmethacrylate; 4mol%, DMAA, N,N-dimethylacrylamide, 88mol%; MBA, N,N’-methylenebisacrylamide, 8mol%) referred to as MTEMA–DMAA-4–8, behaves as a macromolecular ligand towards PdII and AuIII in water (Pd) and acetonitrile (Au). Mn/resin complexes are easily reduced with NaBH4 in water to M0/resin composites. The swollen polymer framework of MTEMA–DMAA-4–8 is seen to act as a “mold” leading to the production of ca. 2.5nm nanoclusters for both elements. M0/MTEMA–DMAA-4–8 composites exhibit useful catalytic properties in various chemical transformations, under mild conditions in water. [Copyright &y& Elsevier] |
