由F-烷基格氏试剂制备半氟化的酮R = CO = R F,其中F-烷基链(C 8 F 17或C 6 F 13)直接与羰基键合。与相应的酰氯相比,酰基酸酐(RCO)2 O在这些有机金属衍生物上的反应构成了通往这些酮的特别竞争的途径。还通过(F-烷基)炔烃R的硫酸汞催化水合得到的甲基(F-烷基)酮˚F CCH。

The ‘one-pot’ synthesis of polyfluorinated isoxazolines and isoxazoles by 1,3-dipolar cycloaddition between arylaldoximes and different fluorinated olefinic and acetylenic compounds in the two-phase medium of CHCl3-NaOCl is described. The different characteristics of adducts are related and the regioselectivity of the reaction discussed.
