  一种通过胺质子重氮化对芳香族和杂环化合物进行碘化的新的一步有效方案

  摘要：

  我们开发了一种方便的一步制备芳香族和一些杂环碘化物的方法，方法是在室温下用 KI/NaNO2/p-TsOH 体系在乙腈中对芳香胺进行连续重氮化碘化。该方法具有一般特征，允许从相应的胺中以 50-90% 的收率获得在不同位置具有供体或受体取代基的芳基碘化物。

• A Mild and Convenient Synthesis of 1,2,3-Triiodoarenes via Consecutive Iodination/Diazotization/Iodination Strategy

  A mild and convenient synthesis of 1,2,3-triiodoarenes has been developed. This method consists of two steps which can be performed on multigram scale with moderate to excellent yields. This report discloses a practical synthesis of 1,2,3-triiodoarenes and 1,2,3-trihaloarenes that is general in scope, operationally simple, scalable, and is easy to workup and to purify. We also report the first regioselective transmetalation reaction of 1,2,3-triiodoarenes to provide ortho-diiodoaryl derivatives, which are useful building blocks and indeed are hard to make by other means.

  我们开发了一种温和、简便的 1,2,3-三碘烯烃合成方法。该方法由两个步骤组成，可在多克级规模上进行，产率为中等至极佳。本报告揭示了 1,2,3-三碘烯烃和 1,2,3-三卤代烯烃的实用合成方法，该方法范围广泛、操作简单、可扩展、易于加工和纯化。我们还首次报告了 1,2,3-三碘烯烃的区域选择性反金属化反应，以提供正二碘芳基衍生物，这些衍生物是有用的构筑基块，实际上很难通过其他方法制造。

• Direct polyiodination of benzenesulfonic acid
  作者：Daniell Lewis Mattern、Xinhua Chen

  DOI：10.1021/jo00020a036

  日期：1991.9

  Direct aromatic polyiodination of benzenesulfonic acid (using I2 and H5IO6 in H2SO4 at room temperature) was performed to test the possible intermediacy of C6H5SO3H in the corresponding direct polyiodination of benzene to C6H2I4. The major product from C6H5SO3H was 3,4,5-triiodobenzenesulfonic acid (4). In contrast, no 4 was formed in the C6H6 reaction, showing that no significant sulfonation of C6H6 to C6H5SO3H occurred during benzene iodination. Compound 4 itself was shown to be inert under the reaction conditions. A pathway is proposed from C6H5SO3H to the other reaction products (C6I6, C6I5H, two C6I4H2 isomers, and 3,4,5-triiodophenol), which therefore avoids the intermediacy of 4.
