Kim, HS Kim, JJ Kwon, HN Chung, MJ Lee, BG Jang, HG 2024-01-21T11:11:09Z 2024-01-21T11:11:09Z 2021-09-04 2002-01-01 0021-9517 https://pubs.kist.re.kr/handle/201004/139856 The poly(4-vinylpyridine)-supported zinc halide catalysts, prepared from a reaction of ZnX2 and poly(4-vinylpyridine), exhibit high selectivity and activity for the coupling reaction of CO2 and ethylene oxide or propylene oxide. Solid NMR characterization of the poly(4-vinylpyridine)-supported ZnBr2 catalyst and its reaction product with propylene oxide and/or CO2 show that a pyridinium/alkoxy ion-bridged zinc bromide complex is functioning as an active species, such as in the homogeneous catalysis with L2ZnBr2 (L pyridine or methyl-substituted pyridine).
