    • A process for the synthesis of (per)fluorinated monofunctional carbonyl compounds having the following formula:F-A-(R F ) t -B-C(O)X 1 wherein: X1 = F, CF3; t = 0, 1; A, B equal to or different from each other, are independently C1-C5 (per)fluoroalkylene groups or C1-C5 (per)fluorooxyalkylene groups; RF is -Rf1-, C1-C20 perfluoroalkylene, -ORf1O-; or -ORf2-, wherein Rf2 is a perfluorooxyalkylene chain; wherein the carbonyl groups of a (per)fluorinated di-functional carbonyl compound of formula (III):X2(O)C-A-(RF)t-B-C(O)X1 wherein: X1, RF, t, A and B have the above meanings; X2, equal to or different from X1, has the same meanings as X1; are partially fluorinated with elemental fluorine in the presence of a catalyst having formula MeFy.zHF, Me being an alkaline or alkaline-earth metal or Ag, y = 1 or 2, z an integer from 0 to 4, carrying out said reaction at a temperature higher than a temperature such that it leads to the formation of C(O)FX2.
    • F-A-(RF)t-B-C(O)X1其中:X1 = F,CF3; t = 0,1; A,B彼此相同或不同,独立地为C 1 -C 5(全)氟亚烷基或C 1 -C 5(全)氟氧亚烷基; RF是-Rf1-,C1-C20全氟亚烷基,-ORf1O-; 或-ORf2-,其中Rf2是全氟氧化烯链; (III)的(全)氟化双官能羰基化合物的羰基:其中:X 1,R F,t,A和B具有上述含义 ; X2与X1相同或不同,与X1具有相同的含义; 在具有式MeFy.zHF,Me为碱金属或碱土金属或Ag,y = 1或2,z为0-4的整数的催化剂存在下,用元素氟部分氟化,在 温度高于一定温度以致导致形成C(O)FX2。
