Abstract
Poly(lactic acid) (PLA) was functionalized at the polymer chain end with nitrogen-containing aromatic groups such as pyridine and 2,2′-bipyridine by means of Sn(II)-catalyzed ring-opening polymerization. e obtained macroligands along with the corresponding stereocomplexes were suitable ligands to stabilize Pd(II) and Pd-nanoparticles (NPs). e nature of the introduced ter- minal group plays a key role in the successful stabilization of small Pd-NPs in the course of the catalytic oxidation and reduction reactions, favorably in uencing hence the catalytic activity and chemoselectivity of the catalytic reactions. e PLA-based polymer backbone proved to be resistant against transesteri cation reactions under real catalytic conditions and to signi cantly increase its thermal stability in the presence of Pd-NPs.File | Dimensione | Formato | |
