| 摘要 |
The present disclosure is directed, in part, to methods of synthesizing a poly(ethylene carbonate) polymer from the reaction of ethylene oxide (EO) and carbon dioxide (CO2) in the presence of a metal complex. The present disclosure also provides novel metal complexes. In one aspect, the metal complex is of the formula (I), wherein R1, R2, R3, M, X and Ring A are as defined herein.; |

1. A method of synthesizing a poly(ethylene carbonate) polymer, wherein the polymer is made up of Y, and optionally Z, and wherein the percentage of Y is greater than the percentage of Z, the method comprising reacting ethylene oxide and carbon dioxide in the presence of a metal complex, wherein the metal complex is of the formula: wherein: M is a metal selected from zinc, cobalt, chromium, aluminum, titanium, ruthenium or manganese; X is absent or is a nucleophilic ligand; each instance of R1, R2, and R3 is, independently, selected from hydrogen, halogen, optionally substituted aliphatic, optionally substituted heteroaliphatic, optionally substituted aryl, and optionally substituted heteroaryl, or R1 and R2, or R2 and R3, are joined to form an optionally substituted aryl or optionally substituted heteroaryl ring; and Ring A forms an optionally substituted 5- to 6-membered ring. |
