全氟链烷磺酸酐[(R F SO 2)2 O; R F= CF 3,C 2 F 5,C 4 F 9 ],与母体酸混合,热分解得到相应的全氟烷基全氟链烷磺酸盐(R F SO 3 R F),并释放出SO 2。如果酸酐和酸中的全氟烷基部分不同,则获得对称和不对称酯的混合物。从结果推导了离子双分子机理,并提出了一种新的容易合成的对称全氟化磺酸酯的新方法。

Cleavage of boron tris-trifluoromethanesulfonate(triflate) and boron tris-pentafluoroethanesulfonate(pentflate) was studied at 200°C. Complete cleavage giving borontrifluoride, sulfur dioxide, carbonyl fluoride (trifluoroacetyl fluoride), triflic (pentflic) anhydride, triflic (pentflic) triflate (pentflate) and boric acid was observed. A mechanism for the cleavage based on formation of the identified
Perfluoroalkanesulfonic anhydrides (RFSO2)2O when mixed with acids decompose into perfluoroalkanesulfonic esters RFSO2ORF, thereby providing a new facile synthesis of these esters from perfluoroalkanesulfonic acids and phosphorus pentoxide.
全氟链烷磺酸酐(R F SO 2)2 O与酸混合时分解为全氟链烷磺酸酯R F SO 2 OR F,从而提供了一种由全氟链烷磺酸和五氧化二磷合成这些酯的新方法。
