在氟两相体系中，金属双（全氟辛烷磺酰基）酰胺是比类似的三氟甲磺酸盐更好的刘易斯酸催化剂，无论是对反式异构化，直接异构化，还是对Friedel-Crafts酰化或Baeyer-Villiger氧化反应都是如此。这些催化剂选择性地溶于低氟相中，并且可以简单地通过相分离来回收。此外，在大多数情况下，这些催化剂可以重复使用而不降低活性。
In fluorous biphase system, metal bis(perfluorooctanesulfonyl)amides are better Lewis acid catalysts than the analogous triflates toward either transesterifications, or direct esterifications, or Friedel–Crafts acylations or Baeyer–Villiger oxidations. These catalysts are selectively soluble in lower fluorous phase and can be recovered simply by phase separation. Furthermore, these catalysts can be reused without decrease of activity in most cases.
