thiolation reaction of 1,4-dihalides with sulfides has been developed for selectively synthesizing 2-trifluoromethyl benzothiophenes and benzothiazoles. In the presence of CuI, a variety of 2-halo-1-(2-haloaryl)-3,3,3-trifluoropropylenes smoothly underwent the thiolation annulation with Na2S to afford 2-trifluoromethyl benzothiophenes in moderate to good yields. Moreover, the conditions are compatible with
已经开发出铜催化的1,4-二卤化物与硫化物的双硫醇化反应,用于选择性合成2-三氟甲基苯并噻吩和苯并噻唑。在CuI存在下,各种2-卤代-1-(2-卤代芳基)-3,3,3-三氟丙烯顺利地与Na 2 S进行硫醇化环化反应,以中等至良好的产率得到2-三氟甲基苯并噻吩。此外,在NaHS和K 3 PO 4的存在下,该条件与N-(2-卤代芳基)三氟乙酰亚氨基酰氯是相容的,从而产生了2-三氟甲基苯并噻唑。
