碘催化吲哚衍生物与二芳基二碲醚芳碲化反应制备3-芳碲基吲哚

Iodine-Catalyzed Telluration of Indole Derivatives with Diarylditellurides for Synthesis of 3-Aryltellurylindoles

在20mol%K2S2O8存在下,20mol%I2催化吲哚衍生物与二芳基二碲醚反应,高产率获得一系列3-芳碲基吲哚化合物.该反应对不同吲哚衍生物和二芳基二碲醚均具有较好的适用性.此外,该方法具有反应条件温和、产率高、原子经济性等优点,为3-芳碲基吲哚化合物的制备提供高效的路径.

In the presence of 20 mol%K2S2O8,a variety of 3-aryltellurylindoles were obtained in high yields via the telluration of indole dervatives with diarylditellurides catalyzed by 20 mol%I2.This process tolerates a wide spectrum of different indole derivatives and diarylditellurides.Other advantages include mild reaction conditions,high yields and atom economy,and an efficient route to 3-aryltellurylindoles is afforded.
