Selective reaction of hexafluoropropylene oxide with perfluoroacyl fluorides

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).

摘要（中）：

提供了一种用于使六氟环氧丙烷（HFPO）与根据式X-Rf-COF（II）的全氟酰基氟化物反应的方法，以选择性地制备根据式X-Rf-CF2-O-CF（CF3）COF的单加成产物（I），其中加成产物相对于加合产物的选择性为90％或更大或更通常为95％或更高。提供连续或重复分批的方法，包括以下步骤：a）提供X-Rf-COF（II），氟化物盐和极性溶剂的混合物; b）加入六氟环氧丙烷（HFPO），其量使得X-Rf-COF保持摩尔过量的HFPO至少10％，并使X-Rf-COF与HFPO反应; c）从六氟环氧丙烷（HFPO）和X-Rf-COF的加成产物的混合物中分离未反应的X-Rf-COF; 和d）重复步骤a）使用在步骤c）中分离的未反应的X-Rf-COF。
