An oxidative copper-mediated double trifluoromethylselenolation of terminal 2-alkynylanilines using [(bpy)CuSeCF3]2 is reported, providing a moderately efficient and convenient approach to 2,3-bis(trifluoromethylseleno)indoles. Mechanistic studies show that a cascade sequence of oxidation, trifluoromethylselenolation, 5-endo-dig cyclization, and elimination is involved in this transformation.
报道了使用 [(bpy)CuSeCF 3 ] 2对末端 2-炔基苯胺进行氧化铜介导的双三氟甲基硒化反应,为 2,3-双(三氟甲基硒代)吲哚提供了一种适度有效且方便的方法。机理研究表明,氧化、三氟甲基硒化、5 - endo - dig环化和消除的级联序列参与了这种转化。
