  • Title: Trifluoromethylation of perfluorinated diacylfluorides: synthesis of the diketone CF3C(O)CF2C(O)CF3 and of new perfluorinated diol (CF3)2C(OH)CF2C(OH)(CF3)2.
    Author: Corti S, Pennington WT, DesMarteau DD.
    Journal: Acta Chim Slov; 2013; 60(3):556-60. PubMed ID: 24169709.
    Abstract:
    Perfluoromalonyl difluoride reacts with TMS-CF3 (1:1) in the presence of KF to give the new diketone CF2(C(O)CF3)2. A large excess (5:1) of TMS-CF3 results in the presumed potassium dialkoxide [(CF3)2COK]2CF2 which yields the 1,3-ditertiarydiol [(CF3)2C(OH)]2CF2 on reaction with H2SO4.
