Stereoselective synthesis of biodegradable polymers by salen-type metal catalysts

Zeolite-encapsulated copper(ii) complexes with NNO-tridentate Schiff base ligands: catalytic activity for methylene blue (MB) degradation under near neutral conditions

“…[8][9][10][11] Schiff base complexes possess interesting physical properties and are widely applied in medicine, materials, and as catalysts. [12][13][14] Copper-based complexes acting as alternatives to expensive metals, have been employed in the degradation of dyes, and exhibit superior reactivity. [15][16][17] However, there are several disadvantages to homogenous catalysts that prevent their application, such as the inability to achieve easy separation and high recyclability of these catalysts.…”

PET recycling under mild conditions via substituent-modulated intramolecular hydrolysis

“…Compared with them, transition metal complexes have shown advantages due to their structure tunability. [12][13][14][15][16][17] For instance, Zn(II)-and Mg(II)-complexes with various ligand structures can facilitate the glycolysis of PET. [12][13][14] Ru(II)-complexes catalyze the hydrogenolysis of PET with high tolerance to impurities.…”

Transformation of Styrene into Biodegradable Polymer through In Situ Epoxidation-Copolymerization Using Tandem Polymeric Catalysts

“…After optimizing the Mn:Al ratio of the polymeric catalyst (1:6), the contents of the byproducts PhAD and BzH could be suppressed to <1 and 5.6%. This work proposed a reliable ISECOP strategy for transforming St into biodegradable polyesters, which may provide a greener pathway for the utilization of commodity olefins.…”
