富电子的芳烃,如二甲氧基苯、吡咯、吲哚、苯并噻吩等在室温条件下,以六氟异丙醇为溶剂,可与酰氯发生分子间傅-克酰基化反应,无需加路易斯酸,且溶剂可回收。24例收率34%~93%。
Electron-rich aromatics, such as dimethoxybenzene, pyrrole, indole, benzothiophene and the like can be intermolecular Fu-Ke acylation with acid chloride at room temperature with hexafluoroisopropanol as solvent, without adding Lewis acid, and solvent recoverable. 24 cases of 34% to 93% yield.
