Abstract
In this paper, a novel air-stable triphenylbismuth bisperfluorooctanesulfonate was synthesized by treatment of moisture-sensitive triphenylbismuth dichloride with silver bisperfluorooctanesulfonate in anhydrous CH2Cl2 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.
