applications. This approach enabled double C–H thiolation at the C2 and C3 of the indole in one pot. The mechanism studies suggested the thiolation was realized through the sulfoxonium salt rather than sulfenyl carboxylate.
描述了在 Pummerer 型条件下吲哚与硫代硫酸盐的无碱双烷基硫醇化反应。用 2,2,2-三氟乙酸酐活化的硫代硫酸盐被证明是一种适用于广泛应用的有效硫醇化试剂。这种方法能够在一锅中在吲哚的 C2 和 C3 上进行双 C-H 硫醇化。机理研究表明,硫醇化是通过氧化鎓盐而不是亚磺基羧酸盐实现的。
