  Chromium complexes with tridentate NN′O Schiff base ligands as catalysts for the coupling of CO2 and epoxides

  摘要：

  New Cr(III) hexacoordinated complexes with tridentate NN'O-donor Schiff base ligands, M(NN'O)(2)Cl, have been prepared. They form active catalytic systems for the coupling of epoxides and carbon dioxide in the presence of co-catalysts. Best results were obtained with the complex with N-(2-pyridylmethyl)-3,5-ditert-butyl-salicylaldimine (1) ligand and a co-catalyst. Cyclohexene oxide reacts with carbon dioxide in the presence of these catalysts to form mixtures of polycarbonate (PC) (productivity up to ca. 900 g PC/g Cr) and cyclic carbonate depending on the co-catalyst and conditions employed. Cyclopentene, styrene and propylene oxides form selectively the cyclic carbonates at the conditions studied (epoxide conversion up to 97%). Although some of the co-catalysts are also active for the cycloaddition, the presence of both complex and co-catalyst has proved to be beneficial. (C) 2013 Elsevier B.V. All rights reserved.
