    摘要： A method is provided for reacting hexafluoropropylene oxide (HFPO) with a perfluoroacyl fluorides according to the formula XnullRfnullCOF (II) to selectively produce a monoaddition product according to the formula XnullRfnullCF2nullOnullCF(CF3)COF (I), wherein selectivity for the monoaddition product over the biaddition product is 90% or greater or more typically 95% or greater. A continuous or repeated-batch process is provided comprising the steps of: a) providing a mixture of XnullRfnullCOF (II), a fluoride salt, and a polar solvent; b) adding hexafluoropropylene oxide (HFPO) in an amount such that XnullRfnullCOF remains in molar excess of HFPO by at least 10% and reacting XnullRfnullCOF with HFPO; c) separating unreacted XnullRfnullCOF from a mixture of addition products of hexafluoropropylene oxide (HFPO) and XnullRfnullCOF; and d) repeating step a) using unreacted XnullRfnullCOF separated in step c).
