  在温和条件下碘催化亚磺酸钠与苯并三唑的N-磺酰化

  摘要：

  开发了一种新的方便的程序，通过分子间碘作为催化剂，通过SN键形成反应，由亚磺酸钠和苯并三唑制备N-磺酰基苯并三唑。该催化自由基磺酰化反应在室温下在空气中于中性条件下有效地进行，并且反应时间短，从而以良好的收率得到相应的N-磺酰基苯并三唑，从而扩展了分子碘在有机合成中的催化应用。

  ABSTRACT A convenient procedure is developed for the preparation of N-sulfonylbenzotriazoles from sodium sulfinates, benzotriazoles, and sodium bromide in the present of m-chloroperbenzoic acid as oxidant. This radical sulfonylation proceeds efficiently at room temperature under neutral conditions, affording the corresponding N-sulfonylbenzotriazoles in moderate to good yields in a short time.
