In fluorous biphase system, hafnium(IV) bis(perfluorooctanesulfonyl)amide complex (Hf[N(SO2C8F17)2]4) was found to be a highly reactive and recyclable Lewis acid catalyst for Friedel–Crafts acylation and Prins reaction at significantly low catalyst loadings (≤1 mol%). In these reactions, Hf[N(SO2C8F17)2]4 is selectively soluble in the lower fluorous phase and can be recovered simply by phase separation
在氟双相体系中,发现found (IV)双(全氟辛烷磺酰基)酰胺配合物(Hf [N(SO 2 C 8 F 17)2 ] 4)是一种高反应性和可循环利用的路易斯酸催化剂,用于Friedel-Crafts酰化和普林斯在极低的催化剂负载量(≤1mol%)下进行反应。在这些反应中,Hf [N(SO 2 C 8 F 17)2 ] 4选择性地溶解在低氟相中,并且可以简单地通过相分离来回收。此外,催化剂可以重复使用而不会降低活性。
