For the first time, we have used activated alumina balls (3–5 mm diameter) for amide synthesis from carboxylic acids (unactivated) and amines (unactivated) under neat reaction conditions that produce no toxic by-products and has the advantages of being low-cost, easily available, heterogeneous, reusable and environmentally benign with no troublesome/hazardous disposal of the catalyst.
我们首次使用活性氧化铝球(直径3–5毫米) 酰胺 合成自 羧酸 (未激活)和 胺类 (未活化),在不产生有毒副产物的纯净反应条件下,具有低成本,易于获得,异构,可重复使用且对环境无害的优点,而不会造成麻烦/危险的处置 催化剂。
