  Electrolytic Reactions of Fluoroorganic Compounds. 14. Regioselective Anodic Methoxylation of N-(Fluoroethyl)amines. Preparation of Highly Useful Fluoroalkylated Building Blocks

  摘要：

  Anodic methoxylation of various types of N-(fluoroethyl)amines, ArRNCH(2)R(f) (R(f) = CF3, CHF2, CH2F, etc.) has been systematically studied and it was found that a methoxy group was exclusively or preferentially introduced into the position a to the fluoromethyl (R(f)) group, depending on the R(f) and R groups. The effect of the R(f) group on the promotion of the anodic alpha-methoxylation decreased in the order CF3, CHF2, and CH2F. This remarkable promotion effect and unique regioselectivity can be explained mainly in terms of the alpha-CH kinetic acidities of the cation radicals formed by one-electron oxidation of the amines. The alpha-methoxylated products are highly useful precursors for the construction of carbon-carbon bonds alpha to the trifluoromethyl and difluoromethyl groups, which is difficult by other methods.

• Trifluoroacetylation of amines with trifluoroacetic acid in the presence of trichloroacetonitrile and triphenylphosphine

  We developed a mild and convenient trifluoroacetylation process for amines using a combination of trichloroacetonitrile and triphenylphosphine. The reaction that we designed is applicable to the trifluoroacetylation of a wide variety of amines, including amines with stereogenic centers, which underwent trifluoroacetylation without racemization.

  An electrostatically directed meta borylation of sterically biased and unbiased substrates is described. The borylation follows an electrostatic interaction between the partially positive and negative charges between the ligand and substrate. With this strategy, it has been demonstrated that a wide number of challenging substrates, especially 4-substituted substrates, can selectively be borylated at

  描述了空间偏压和无偏压底物的静电定向代谢硼化。硼酸化遵循配体和底物之间部分正电荷和负电荷之间的静电相互作用。使用这种策略，已经证明大量具有挑战性的底物，尤其是 4 取代底物，可以在间位选择性地硼酸化。此外，未取代的底物也表现出优异的间位选择性。该反应采用实验室稳定的配体并在较温和的温度下进行，无需合成庞大而复杂的配体/模板。
