investigated in Friedel–Crafts benzoylation under microwave irradiation. Friedel–Crafts benzoylation with benzoyl chloride of a variety of arenes containing electron-rich and electron-poor rings using bismuth triflate under microwave irradiation is described. This method allows the preparation of aryl ketones under solventless conditions in good to excellent yields and short reaction time. Bismuth triflate
摘要 研究了金属三氟甲磺酸盐在微波辐射下的 Friedel-Crafts 苯甲酰化反应中的催化活性。描述了在微波辐射下使用三氟甲磺酸铋与含富电子和缺电子环的各种芳烃的苯甲酰氯的 Friedel-Crafts 苯甲酰化反应。该方法允许在无溶剂条件下以良好至极好的收率和较短的反应时间制备芳基酮。三氟甲磺酸铋很容易回收并重复使用五次,而催化活性没有显着损失。图形概要
