Synthesis of a well-defined end-chain macrophotoinitiator of poly(ε − caprolactone) by combination of ring-opening polymerization and click chemistry

Synthesis of poly(disulfide)s with narrow molecular weight distributions via lactone ring-opening polymerization

We report the first example of controlled polymerization of poly(disulfide)s with narrow molecular weight distributions. 1,4,5-oxadithiepan-2-one (OTP), a disulfide-containing 7-membered ring lactone, was polymerized by using the diphenylphosphate (DPP) catalyzed lactone ring-opening polymerization method. The polymerization proceeded in a living manner, and the resulting polymers displayed very narrow polydispersity index (PDI) values below 1.1 and excellent backbone degradability responding to reducing conditions and UV irradiation.

Design, synthesis and characterization of novel dioxime ligand-based cobaloxime compounds for application in the coupling of CO2 with epoxides

Novel dioxime-based cobaloxime complexes have been obtained by click chemistry and used as catalysts for the conversion of CO₂ to a cyclic carbonate without using any solvent.
