A cascade oxidative trifluoromethylthiolation and cyclization of N-[(3-aryl)propioloyl]indoles with AgSCF3 is described. This protocol allows for the synthesis of novel bis(trifluoromethylthiolated) or trifluoromethylthiolated pyrrolo[1,2-a]indol-3-ones in moderate to good yields. Mechanistic investigations indicated that radical processes were probably involved in these transformations.

级联三氟甲基硫醇化和N-[（3-芳基）丙酰基]吲哚的环化。

描述了级联氧化三氟甲硫基化和N-[（3-芳基）丙酰基]吲哚与AgSCF3的环化。该方案允许以中等至良好的产率合成新型的双（三氟甲基硫代）或三氟甲基硫代的吡咯并[1,2-a]吲哚-3-酮。机理研究表明，激进过程可能参与了这些转变。
