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.
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.
