Efficient Production of Poly(Cyclohexene Carbonate) via ROCOP of Cyclohexene Oxide and CO2 Mediated by NNO-Scorpionate Zinc Complexes. Polymers 2020, 12, 2148.2073-4360http://hdl.handle.net/10115/17331PreprintNew mono- and dinuclear chiral alkoxide/thioalkoxide NNO-scorpinate zinc complexes were easily synthesized in very high yields, and characterized by spectroscopic methods. X-ray diffraction analysis unambiguously confirmed the different nuclearity of the new complexes as well as the variety of coordination modes of the scorpionate ligands. Scorpionate zinc complexes 2, 4 and 6 were assessed as catalysts for polycarbonate production from epoxide and carbon dioxide with no need for a co-catalyst or activator under mild conditions. Interestingly, at 70 °C, 10 bar of CO2 pressure and 1 mol % of loading, the dinuclear thioaryloxide [Zn(bpzaepe)2{Zn(SAr)2}] (4) behaves as an efficient and selective one-component initiator for the synthesis of poly(cyclohexene carbonate) via ring-opening copolymerization of cyclohexene oxide (CHO) and CO2, affording polycarbonate materials with narrow dispersity valuesengAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/QuímicaScorpionate zinc complexesring-opening copolymerization (ROCOP)CO2 fixationpoly(cyclohexene carbonate) productioninfo:eu-repo/semantics/preprint10.3390/polym12092148info:eu-repo/semantics/openAccess23 Química
