    Novel ipso-Substitution of p-Sulfinylphenols through the Pummerer-Type Reaction:  A Selective and Efficient Synthesis of p-Quinones and Protected p-Dihydroquinones
    摘要:
    The treatment of p-sulfinylphenols 3a-q with trifluoroacetic anhydride caused a Pummerer-type reaction on aromatic rings and concomitant desulfurization to give mixtures of the corresponding p-dihydroquinones 9 and p-quinones 10, which were subsequently oxidized under mild conditions to provide high yields of p-quinones 10. On the other hand, the treatment of p-(phenylsulfinyl)-phenyl ethers 6 with trifluoroacetic anhydride in the presence of styrene caused the direct ipso-substitution of the sulfinyl groups into trifluoroacetoxy groups, giving the protected dihydroquinones 14 in high yields. Both types of reactions were generally completed below room temperature within 1 h and compatible with various functional groups such as the allyl, carbonyl, ester, amide, and silyloxy groups. The preparation of the p-sulfinylphenols 3 and the silyl ethers 6 is also described through p-specific thiocyanation of phenols followed by the Grignard reaction and oxidation.

    摘要:
    已使用1-氯-1,2-苯并恶唑3-(1H)-一(1)和(三甲基甲硅烷基)异硫氰酸酯(TMSNCS)的组合研究了芳族化合物的硫氰酸化。与富电子芳族化合物的反应进行得很顺利,以高收率提供了硫氰酸化产物,而缺电子的杂芳族化合物不适合该反应。在这些反应中,区域选择性通常很高。还研究了产物的转化以证明反应的效用。基于NMR实验,我们建议原位生成氯化硫氰作为活性物质。

    A combination of PhICl2 and Pb(SCN)2 is effective for the p-selective thiocyanation of various types of p-unsubstituted phenols and naphthols 1 to give p-thiocyanatophenols and naphthols 3. The reaction proceeded at 0°C to room temperature in good to quantitative yields. Twenty-five examples are given, in which various functional groups, such as chloro, allyl, carbonyl, ester, amide, and primary hydroxyl groups, are shown to be compatible with this reaction.
    PhICl2 和 Pb(SCN)2 的组合可有效地对各种类型的对未取代苯酚萘酚 1 进行对选择性硫氰酸化,从而得到对硫氰酸苯酚萘酚 3。反应在 0°C 至室温下进行,产率高至定量。文中给出了 25 个例子,表明基、烯丙基、羰基、酯基、酰胺基和伯羟基等各种官能团与该反应相容。
