Stable Long-Chain Fluoroxy Compounds and Their Chemistry

Article abstract of DOI:10.1021/jo00220a004

Certain alkali metal salts of long-chain perfluorinated acids were reacted with nitrogen-diluted fluorine to produce oxidative solutions.The reaction conditions can be controlled to afford mainly acyl hypofluorites (R_fCOOF) or fluoroxy species fCF2OF and R_fCF(OF)2> which have been identified by both chemical reactions and 19F NMR studies.These solutions are useful in electrophilic fluorination reactions and as initiators for the polimerization of some fluorinated monomers.As initiators they produce polymers with fewer reactive end groups when compared with standard methods of initiation.
