acid-4-hydrogen sulfate, supported on silica gel was prepared and characterized by Mass spectroscopy, 1H NMR, 13CNMR, FT IR and elemental analysis (CHN) methods. This heterogenized catalyst can be used as an efficient catalyst for the acylation of alcohols, phenols, and amines with acetic anhydride under mild and solvent-free conditions. Simple work-up, stability of the catalyst, nontoxicity and good
在本工作中,制备了负载在硅胶上的L-吡咯烷-2-羧酸-4-硫酸氢盐,并通过质谱,1 H NMR,13 CNMR,FT IR和元素分析(CHN)方法进行了表征。这种杂化的催化剂可以用作在温和且无溶剂的条件下用乙酸酐酰化醇,酚和胺的有效催化剂。简单的后处理,催化剂的稳定性,无毒和良好的高收率是这项工作的优势。
