制备了磁性纳米粒子负载的季铵盐和季鏻盐，并对其作为相转移催化剂进行了评价。其中一些化合物表现出与四正丁基碘化铵相当的活性。使用外部磁体容易地分离催化剂，并且可重复使用而不会显著损失其催化效率。
Magnetic nanoparticles-supported quaternary ammonium and phosphonium salts were prepared and evaluated as phase-transfer catalysts. Some of them exhibited good activities that were comparable to that of tetra-n-butylammonium iodide. The catalysts were readily separated using an external magnet and reusable without significant loss of their catalytic efficiency.
