simple filtration process and recycled further for up to four consecutive recycle without any loss of activity and selectivity. The protocol is advantageous due to the ease in handling of the catalyst, simple workup procedure, phosphine-free, and effective catalyst recyclability. The amidation of arylhalides with alkyl/aryl isocyanides to give the corresponding amides using polymer-supported palladium–N-heterocyclic

salts, or dimethyl(phenyl)sulfonium salts with trifluoroacetamides affords substituted aromatic amides in good to excellent yields. These nickel-catalyzedreactions are enabled by C–CF3 bond activation using Dy2O3 as an additive. The current protocol provides versatile and scalable routes for accessing a wide variety of substituted aromatic amides. Moreover, the protocol described in this work overcomes
酰胺键在天然和合成有机分子中很突出,在各个领域都具有活性。在众多的酰胺合成方法中,取代预先存在的 (O)C-N 部分是一种尚未开发的酰胺合成策略。在这项工作中,我们公开了一种用于脂肪族和芳香族三氟乙酰胺脱氟芳基化产生芳香族酰胺的新方案。芳基硼酸、三甲氧基苯基硅烷、二芳基碘盐或二甲基(苯基)锍盐与三氟乙酰胺的机械化学诱导反应以良好至极好的收率提供取代的芳族酰胺。这些镍催化的反应是通过使用 Dy 2 O 3的 C–CF 3键活化来实现的作为添加剂。当前的协议提供了通用且可扩展的路线,用于访问各种取代的芳香酰胺。此外,这项工作中描述的协议克服了先前报告的方法中的缺点和局限性。
