efficient method for the construction of aryl trifluoromethyl selenoethers from the corresponding aryl halides in the presence of Ni(COD)2 and an appropriate ligand is reported. Various aryl iodides, bromides, and chlorides were smoothly converted in this reaction by simply varying the ligand, which afforded aryl and heteroaryl trifluoromethyl selenoethers in good to almost quantitative yields. The reaction
在Ni(COD)2存在下由相应的芳基卤化物构建芳基三氟甲基硒醚的便捷有效方法并报道了合适的配体。通过简单地改变配体,各种芳基碘化物,溴化物和氯化物就可以在该反应中平稳地转化,从而以良好或几乎定量的产率提供了芳基和杂芳基三氟甲基硒醚。该反应也适用于药物样分子的合成。这项工作是有关芳基氯的三氟甲基硒化的第一份报告。本发明的镍催化方法的优点包括温和的反应条件,良好的官能团耐受性,廉价的试剂,易于操作以及不使用额外的添加剂。该方案允许直接和可靠地获得三氟甲基硒化物,而三氟甲基硒化物是新药和农用化学品的潜在筛选候选物。
