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。
