本工作合成了一种新型的对空气稳定的路易斯酸性催化剂三苯基铋(V)全氟辛基磺酸盐,该催化剂由对水敏感的三苯基铋二氯化物与全氟辛基磺酸银在无水二氯甲烷溶剂中室温下反应制得.催化活性评价实验表明,在三苯基铋(V)全氟辛基磺酸盐(5.0 mol%)存在下,室温和无溶剂条件下,环氧化合物和胺类的反应有效进行,较高产率地得到了β-氨基醇类化合物.催化剂在重复使用4次之后,反应产率无明显降低.本方法为β-氨基醇的制备提供了一条简单高效的途径.
In this work, we synthesized a novel air-stable Lewis acid catalyst, triphenylbismuth (V) perfluorooctanesulfonate, which is composed of water-sensitive triphenylbismuth dichloride and perfluorooctyl sulfonate Acid silver was prepared by reaction in anhydrous dichloromethane at room temperature.The evaluation of catalytic activity showed that in the presence of triphenylbismuth (V) perfluorooctanesulfonate (5.0 mol%), , The reaction of epoxy compounds and amines was effectively carried out, and the β-aminoalcohols were obtained in high yield.The reaction yield was not obviously decreased after the catalyst was reused for 4 times.The preparation of β-aminoalcohol Provides a simple and efficient way.
