摘要
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 paper, a novel air-stable triphenylbismuth bisperfluorooctanesulfonate was synthesized by treatment of moisture-sensitive triphenylbismuth dichloride with silver bisperfluorooctanesulfonate in anhydrous CH_2Cl_2 at room temperature. Its catalytic assessment results show that the reactions of arylamine and epoxide proceed efficiently in the presence of triphenylbismuth bisperfluorooctanesulfonates 1（5.0 mol%） under solvent-free condition, affording β-amino alcohols in good to excellent yields. The yields of desired products do not reduce obviously after recycling for 4 times of catalyst 1. Hence, a convenient and efficient method for preparation of β-amino alcohols is provided.
