  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.
