prepared and fully characterized by FT-IR, TGA, and SEM. This super acidic solid catalyst shows high catalytic activity for selective acylation of alcohols, phenols, amines, and thiols with anhydrides under solvent-free conditions at room temperature. In addition, this method features an easy to handle solid super acid catalyst and an operationally simple procedure, affording the desired acylated products
摘要制备了三氟甲磺酸官能化的聚乙烯基聚吡咯烷酮,并通过FT-IR,TGA和SEM对其进行了全面表征。这种超酸性固体催化剂在室温下在无溶剂条件下,对醇,酚,胺和硫醇与酸酐的选择性酰化反应具有很高的催化活性。另外,该方法的特征在于易于处理的固体超强酸催化剂和操作简单的步骤,以优异的产率提供了所需的酰化产物。 图形概要
