Generation of size-controlled gold(0) and palladium(0) nanoclusters inside the nanoporous domains of gel-type functional resins

The functional resin poly-MTEMA–DMAA–MBA (MTEMA, 2-(methylthio)ethylmethacrylate; 4 mol%, DMAA, N, N-dimethylacrylamide, 88 mol%; MBA, N, N’-methylenebisacrylamide, 8 mol%) referred to as MTEMA–DMAA-4–8, behaves as a macromolecular ligand towards Pd II and Au III in water (Pd) and acetonitrile (Au)....

Description
Summary:The functional resin poly-MTEMA–DMAA–MBA (MTEMA, 2-(methylthio)ethylmethacrylate; 4 mol%, DMAA, N, N-dimethylacrylamide, 88 mol%; MBA, N, N’-methylenebisacrylamide, 8 mol%) referred to as MTEMA–DMAA-4–8, behaves as a macromolecular ligand towards Pd II and Au III in water (Pd) and acetonitrile (Au). M n /resin complexes are easily reduced with NaBH 4 in water to M 0/resin composites. The swollen polymer framework of MTEMA–DMAA-4–8 is seen to act as a “mold” leading to the production of ca. 2.5 nm nanoclusters for both elements. M 0/MTEMA–DMAA-4–8 composites exhibit useful catalytic properties in various chemical transformations, under mild conditions in water. ▪
