Polyfluorinated organic compounds

Polyfluorinated organic compounds often have much lower boiling points than might be expected. 

A specific challenge remains for the metal-induced cleavage of the strongest bond that carbon can form, the C-F bond [57 f). The functionalization of polyfluorinated organic compounds - important building blocks of chemical, pharmaceutical, and advanced materials industries - would promise a diverse market for such a process. First success in this area is based on the stoichiometric reaction of eq. (9),...

Simons process — Electrochemical polyfluorination reactions of organic compounds are the only efficient way to industrial production of perfluorinated compounds. The reaction proceeds in the solution of KF in liquid HF (b.p. 19.5 °C), where the starting substances as alcohols, amines, ethers, esters, aliphatic hydrocarbons and halo-hydrocarbons, aromatic and heterocyclic compounds, sulfo- or carboxylic acids are dissolved. During anodic oxidation, splitting of the C-H bonds and saturation of the C=C bonds occur and fluorine atoms are introduced.

This volume is the first of a series of biennial reviews concerned with the chemistry of organic, organometallic, and organometalloidal compounds of the fluorocarbon class and of their polyfluorinated analogues. Compounds containing a low proportion of C—F bonds are mentioned only when relevant... 

Fluorinated diacids offer a convenient method for introducing a perfluoro moiety into organic molecules. They are of potential interest in the preparation of polyamides and other fluorinated polymers. A detailed description of the perfluorocarboxyUc acids and their derivatives has been pubflshed (1), and a review article on polyfluorinated linear biflmctional compounds has appeared (35). 

The main characteristics of polyfluorinated compounds are the replacement of most hydrogens by fluorine in the aliphatic chain structure. Some of these organic fluorine compounds are known as perfluorinated, which means that all hydrogens have been replaced with fluorine with a large variety of chemical forms and structures. Because of the diversity of fluoro organic substances, it is important to understand the developed chemical terminology.
