    • 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,其包括将通式(A)的氟化醇:A-CH 2 -OH置于至少一种第一和至少一种第二氧化剂中以产生高度氟化的羧酸或 其通式(B)的盐:A-COO M +,其中M +表示阳离子,式(A)和(B)中的A相同,A表示残基:Rf- [0] p-CX“ Y“ - [0] m-CX'Y' - [0] n-CXY-其中Rf表示可以或可以不含有一个或多个链状氧原子的氟化烷基残基,p,m和n彼此独立地 1或O,X,X',X“,Y,Y'和Y”彼此独立地为H,F,CF 3或C 2 F 5,条件是不是全部X,X',X“,Y, Y'和Y“为H; 或A表示残基: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,其可以含有或不含有一个或多个氟原子, 或者可以不包含一个或多个链状氧原子; 其中所述至少一种第一氧化剂是可以通过第二氧化剂的作用转化成能够氧化氟化醇的反应性物质的化合物。
