摘要: Abstract A polymer supported palladium catalyst, obtained by copolymerization of Pd(AAEMA) 2 [AAEMA − = deprotonated form 2-(acetoacetoxy) ethyl methacrylate] with methacrylate (co-monomer) and ethylene glycol dimethacrylate (cross-linker), exhibited excellent activity selectivity for the hydrogenation quinolines to 1,2,3,4-tetrahydroquinolines in presence NaBH 4 as hydrogen donor water. Both could be maintained at least seven reaction runs. No metal leaching into solution occurred during recycles. TEM analyzes carried out on catalyst showed that active species were nanoparticles having a mean size 3 nm, which did not aggregate
