摘　　要：噁唑烷酮以环氧化合物为起始原料,通过与CO_(2)和胺类化合物反应一步合成,是一种极具经济价值和环境效益的路线。合成了一种大分子轮状离子液体催化剂,考察了催化剂的催化性能,并系统探究了反应条件对催化剂反应活性的影响。结果表明,大分子轮状离子液体催化剂可高效催化CO_(2)与环氧丙烷和苯胺反应合成芳基噁唑烷酮,在优化的反应条件下(150℃,1 MPa, 10 h),芳基噁唑烷酮的收率为87.8%,苯胺转化的选择性为97.1%,可循环使用3次以上。Oxazolidinone is synthesized by the multicomponent reaction of epoxides,CO_(2) and amines,which is a route of great economic value and environmental benefit.Herein,a catalyst of macromolecule colyliform ionic liquid was synthesized.This catalyst showed highly effect for the cycloaddition of CO_(2) with epoxides and aniline to aryl-oxazolidinones.Under the optimization condition(150℃,1 MPa,15 h),the selectivity was 97.1%,yield of aryloxazolidinones could reach above 87.8%,and can be used for three times.
