Aluminum dodecatungstophosphate (AlPW12O40) as a non-hygroscopic Lewis acid catalyst for the efficient Friedel–Crafts acylation of aromatic compounds under solvent-less conditions
Stable and non-hygroscopic aluminum dodecatungstophosphate (AlPW12O40), which is prepared easily from cheap and commercially available compounds was found to be an effective catalyst for Friedel–Crafts acylation reactions using carboxylic acids, acetic anhydride and benzoyl chloride in the absence of solvent under mild reaction conditions.
稳定且不吸湿的十二碳二磷酸铝(AlPW 12 O 40),可以容易地由廉价且可商购的化合物制备,被发现是在不存在羧酸的情况下使用羧酸,乙酸酐和苯甲酰氯进行Friedel-Crafts酰化反应的有效催化剂。在温和的反应条件下使用溶剂。
