Quaternary ammonium salts containing fluorine

In a series of publications on the fluorination of amines and quaternary ammonium salts Rudiger and co-workers have reported their findings on the analyses of the three product containing phases from the reactions, the perfluorinated liquid phase, the gaseous phase, and the so-called HF-phase, which was shown to contain significant quantities of partially fluorinated material, some of which were considered as intermediates in the fluorination process, but also others which remained inert to further reaction [180, 181]. 

Fluorine containing ammonium salts. As amino compounds often have marked physiological action, it seemed worth while to prepare compounds containing both fluorine and a quaternary amino grouping.
