Vinyl bromides were subjected to the trifluoroethoxylation reactions with copper reagent [(phen)2Cu][OCH2CF3] at 80 °C in DMF with the presence of NaOt-Bu to afford the trifluoroethyl vinyl ethers in good yields. A range of functional groups, such as cyano, nitro, alkoxy, trifluoromethyl, halide, and heterocyclic groups were well tolerated. This approach is also amenable to being performed out on gram
在NaO t -Bu存在下,于80℃,在DMF中,使用铜试剂[[phen] 2 Cu] [OCH 2 CF 3 ]对乙烯基溴进行三氟乙氧基化反应,从而以良好的收率得到三氟乙基乙烯基醚。各种官能团,例如氰基,硝基,烷氧基,三氟甲基,卤化物和杂环基均具有良好的耐受性。该方法也适合于以克为单位执行。
