A novel aromaticcyclic carbonate (3) having binaphthyl structure was prepared by the reaction of 2,2′-binaphthol with 4-nitrophenyl chloroformate in the presence of a tert-amine. 3 polymerized very efficiently with potassium tert-butoxide at 20 °C to give corresponding linear polycarbonate with 12800 (/ 1.34) in 94% yield.
通过2,2'-联萘酚与4-硝基苯基氯甲酸酯在叔胺存在下反应制备具有联萘结构的新型芳族环状碳酸酯(3)。3 在 20 °C 下与叔丁醇钾非常有效地聚合,得到相应的线性聚碳酸酯,产率为 12800 (/ 1.34),产率为 94%。
