Ring-opening Polymerization of Lactides Catalyzed by (Benzoimidazolylmethyl)amine Zinc(II) Complexes

Ring opening polymerization of d,l-lactide and ε-caprolactone catalysed by (pyrazol-1-yl)copper(ii) carboxylate complexes

“…Several ligands have been explored to obtain the optimum catalytic performance of metal complexes; including amino-phenolate, [33][34][35] salicylaldimine, 32 formamide, 36,37 pyrazolyl, 30,[38][39][40][41] and benzoimidazolyl. [42][43][44] Pyrazole and its derivatives constitute an important group of Ndonor ligands that have been used because of their attractive coordination chemistry. 45 The structural exibility of pyrazole and pyrazolyl ligands constitute an interesting advantage.…”
