dibromoarenes) reacted with diphenols, catalyzed by CuI/Fe(acac)3 in the presence of K2CO3 in anhydrous DMSO at 110 °C for 7 days under nitrogen atmosphere, to afford macrocyclic aryl ethers effectively. To expand this methodology, a cyclic hepta(p-phenylene oxide) and cyclic deca(p-phenylene oxide) were synthesized in one pot. Some macrocyclic aryl ethers showed strong fluorescence in acetone at 25 °C.
在K 2 CO 3的存在下,在无水DMSO中,氮气氛下,CuI / Fe(acac)3催化二碘芳烃(或二溴芳烃)与二酚反应,在110°C的条件下,在氮气氛下,将其催化7天,从而有效地提供了大环芳基醚。为了扩展该方法,在一个罐中合成了环状七(对苯醚)和环状十(对苯醚)。一些大环芳基醚在25°C的丙酮中显示强荧光。
