式R F CH 2 COCH 3(R F = n -C 3 F 7,n -C 4 F 9,n -C 6 F 13,n -C 8 F 17)的全氟烷基丙酮与氨以及伯和仲的相互作用胺已被研究。在所有情况下,亲核试剂都会先对起始的酮进行脱氟化氢,然后再用亲核试剂取代乙烯基氟原子,从而得到β-二羰基化合物R F C(NR 2)= CH-C(O)CH 3;它们的水解在温和条件下产生相应的β-二酮。全氟烷基丙酮与烷氧基钠反应,生成式R F C(OR)2 CH 2 COCH 3的化合物,其酸性水解作用还会生成β-二酮。

Fluorinated β-diketones have been synthesized in high yield from the one-potreaction of silyl enol ethers with perfluoroalkyliodides initiates with Na2S2O4/NaHCO3, followed by treatment with diethylamine and acid hydrolysis.
氟化的β-二酮是由甲硅烷基烯醇醚与全氟烷基碘的一锅反应以Na 2 S 2 O 4 / NaHCO 3引发,然后用二乙胺处理和酸水解高产率合成的。

The interaction of electrochemically generated radicals in the electrolysis of the perfluorocarboxylic acids R(F)CF2COOH (I), where R(F) = F (a), CF3 (b), C2F5 (c), C3F7 (d), C5F11 (e), and C7H15 (f), with isopropenyl acetate (II) was studied. The dependence of the results of the electrolysis on the adsorption capacity of the anode permits the proposition that the interaction of (II) with the ECG-radicals occurs close to the surface of the electrode. The yield of the perfluoroalkylacetones comprised 30-37%.
