“green” catalyst. The catalyst was synthesised by the reaction of the epichlorohydrin-activated agarose matrix with ammonia solution, which was then treated with Ce(NO3)3 · 6H2O. The catalyst (CAEA) was characterised by FT-IR, far IR, CHN, XRD, TGA, and ICP techniques. CAEA is shown to be an effective and reusable heterogeneous catalyst for the transamidation of carboxamides with amines under solvent-free
本研究报告了固定化在胺化表氯醇活化的琼脂糖基质(CAEA)上的Ce(III)作为“绿色”催化剂的制备和表征。通过表氯醇活化的琼脂糖基质与氨溶液反应合成催化剂,然后用Ce(NO 3)3 ·6H 2处理O.催化剂(CAEA)通过FT-IR,远红外,CHN,XRD,TGA和ICP技术表征。已证明,CAEA是在无溶剂条件下将羧酰胺与胺进行氨基转移的有效且可重复使用的多相催化剂。该催化剂已成功地用于合成多种芳香族和脂肪族酰胺。高效,温和的反应条件,易于处理,简单的分离以及可重复使用性是该催化剂的重要优点。
