Abstract
Pyridine end-capped L-poly(lactide), L,D-poly(lactide) and poly(caprolactone) were synthesized by 4-hydroxymethyl-piridine initiated ROP and employed as macroligands for the square-planar coordination of Pd(II) ions. PdCl2 trans-macrocomplexes were obtained and could further react giving homo- and heteroleptic star-shaped products. Palladium di-acetate macrocomplexes were synthesized and employed as recoverable homogeneous catalysts for aerobic oxidations. V-shaped (Allyl)Pd(II) homo- or heteroleptic macrocomplexes could be synthesized via a stable intermediate. Products were characterized by 1H- and 13C-NMR, UV/Vis-spectroscopy, GPC and DSC analyses.
