[γ-Fe2O3@SiO2-HClO4] (2.5 mol%) has been found to be a capable biocompatible and recyclable catalyst for highly efficient conversion of a variety of alcohols to corresponding amides via modified Ritter reaction in good to excellent yields. Since this heterogeneous catalyst can be simply removed by using an external magnetic device then recovered, it also enhances product purity and promises economic.
的HClO 4 -官能化
二氧化硅涂覆的磁性纳米颗粒[γ-的Fe 2 ö 3 @SiO 2 -HClO 4 ](2.5摩尔%)已被发现是用于各种醇对应高效转化能
生物相容的和可回收的催化剂通过改进的Ritter反应获得酰胺,收率良好。由于可以通过使用外部磁性装置简单地除去这种多相催化剂,然后进行回收,因此,它还可以提高产品纯度,并有望带来经济效益。
