Résumé An efficient and solvent-free procedure for the synthesis of flavones using KHSO4 as a recyclable catalyst is described. The methodology represents an environmentally friendly process in comprehensive consideration compared with other catalytic systems listed in publications. This method provides a clean, simple, solvent-free reaction and useful alternatives to prepare flavones and chromones. The use of KHSO4 catalyst provides excellent yields, also leading to an easy separation and recovery of the catalysts, which allows both low environmental impact and low cost. Other green advantages of the method are the low formation of wastes and the replacement of corrosive, soluble mineral acids.

摘要
本文描述了一种高效无溶剂的黄酮合成程序,采用KHSO4作为可回收催化剂。这种方法在综合考虑下,与其他文献中列出的催化系统相比,代表了一种环保的过程。该方法提供了一种清洁、简单、无溶剂的反应,并为制备黄酮和色酮提供了有用的替代方案。使用KHSO4催化剂可实现优异的产率,同时便于催化剂的分离和回收,这不仅降低了环境影响,还降低了成本。该方法的其他绿色优势包括废物生成少,以及替代腐蚀性可溶性矿酸。
