A new method for the preparation of fluoroalkylthioethers including trifluoromethylthioether and difluoromethylthioether by iridium(I)-catalyzed deoxgenation of fluoroalkylsulfoxides with dimethyl diazomalonate was developed. In the reaction system, dimethyl diazomalonate was used as reducing reagent and the corresponding fluoroalkylthioethers were produced through oxygen atom transfer from fluoroalkylsulfoxides
研究了铱(I)催化重氮丙二酸二甲酯脱氧氟代烷基亚砜制备三氟甲基硫醚和二氟甲基硫醚的新方法。在反应体系中,以重氮丙二酸二甲酯为还原剂,通过氧原子从氟烷基亚砜转移到重氮丙二酸,生成相应的氟烷基硫醚。该方案具有有效的氧原子转移、温和的反应条件和良好的官能团耐受性,为氟烷基硫醚的合成提供了另一种策略。
