摘要四氟硼酸二铁[Fe(Cp)2BF4]是一种高效的路易斯酸催化剂,在室温无溶剂条件下,以苯胺和取代苯胺为亲核试剂进行芳香、脂肪和环环氧化合物的氨解反应,生成61-97%的区域选择性β-氨基醇。在60℃无溶剂条件下,环氧环己烯与脂肪胺开环,得到2-氨基环己醇,产率为33-98%。
Abstract Ferrocenium tetrafluoroborate [Fe(Cp)2BF4] is an efficient Lewis acid catalyst for the aminolysis of aromatic, aliphatic, and cyclic epoxides using aniline and substituted anilines as the nucleophile to provide regioselective β-amino alcohols in 61–97% yields under solvent-free conditions at room temperature. The ring opening of cyclohexene oxide with aliphatic amines gave 2-aminocyclohexanols in 33–98% yields at 60 °C under solvent-free conditions.
