Process for the introduction of fluoro-carbon substituents in organic compounds

摘要

A one pot process for the perfluoroalkylation and/or perfluoroacyloxylation of organic substrates is provided. The process comprises contacting a substrate with a perfluoroalkanoic anhydride in the presence of a an inorganic peroxygen compound at a temperature of greater than 10 DEG C. Substrates that can be perfluoroalkylated and/or perfluoroacyloxylated include alkylbenzenes, halogenated aromatic compounds, alkoxybenzenes, aryl benzenes, and aromatic and aliphatic disulphides. Preferably, the perfluoroalkanoic anhydride is trifluoroacetic anhydride and the inorganic peroxygen compound is sodium percarbonate.
