    • A method for preparing fluorinated carboxylic acids and theirs salts is described comprising subjecting a fluorinated alcohol of the general formula (A): A-CH2-OH to at least one first and at least one second oxidizing agent to produce a highly fluorinated carboxylic acid or their salts of the general formula (B): A-COO M+, wherein M+ represents a cation and wherein A in formulas (A) and (B) is the same and A represents the residue: Rf-[0]p-CX"Y"-[0]m-CX'Y'-[0]n-CXY- wherein Rf represents a fluorinated alkyl residue which may or may not contain one or more catenary oxygen atoms, p, m and n are independently from each other either 1 or O, X, X', X", Y, Y' and Y" are independently from each other H, F, CF3, or C2F5 with the proviso that not all of X, X', X", Y, Y' and Y' ' are H; or A represents the residue: R-CFX- wherein X and R are independently selected from a hydrogen, a halogen, or an alkyl, alkenyl, cycloalkyl, or aryl residue, which may or may not contain one or more fluorine atoms and which may or may not contain one or more catenary oxygen atoms; wherein said at least one first oxidizing agent is a compound that can be converted, by action of the second oxidizing agent, into a reactive species capable of oxidizing the fluorinated alcohol.
    • 描述了制备氟化羧酸及其盐的方法,包括使通式(A)的氟化醇:A-CH 2 -OH经历至少一种第一和至少一种第二氧化剂以产生高度氟化的羧酸或 它们的通式(B)的盐:A-COO M +,其中M +表示阳离子,并且其中式(A)和(B)中的A相同且A表示残基:Rf- [O] p-CX“ 其中Rf表示可以含有或不含有一个或多个悬链氧原子的氟化烷基,p,m和n彼此独立地为 X',X',Y',Y'和Y“各自独立地为H,F,CF 3或C 2 F 5,条件是不是所有的X,X',X” Y'和Y“是H;或者A代表残基:R-CFX-,其中X和R独立地选自氢,卤素或烷基,烯基,环烷基或芳基残基,其可以或不可以 含有一个或多个氟原子 ms并且可能包含或不包含一个或多个悬链氧原子; 其中所述至少一种第一氧化剂是能够通过所述第二氧化剂的作用转化为能够氧化所述氟化醇的反应性物质的化合物。
