The generation of perfluoroalkanoyl fluorides from perfluoroalkyl ethers by Lewis acids RHOCF2RF -> FRH + RFCOF depends mainly upon the nature of the alkyl RH radical.It is necessary to use RH groups with donor character and also electrophilic groups present on the radicals can facilitate the breaking of the RH-O bond.As examples, ethers with Me3SiCH2CH2 or CH2=CH-CH2 groups allowed reactions to occur readily at room temperature or below using common Lewis acids such as ZnCl2, BF3-Et2O, AlCl3.
