提出了一种不含过渡金属的N-芳基酰胺类化合物的合成方法。以乙腈为氮给体,稳定的芳基三氮烯为芳基前体,通过C单键N键的断裂,水为氧源,溴化酸性离子液体(BAILs)为潜在促进剂,在室温下进行了芳基三氮烯与乙腈的胺化反应.值得注意的是,通过启动子BAIL的可重用性进一步证明了该方法的实用性。与传统方法相比,该方法对环境友好,原料稳定,易得,使其在合成N-芳基酰胺方面更具吸引力。
A transition-metal-free synthetic strategy has been developed for the synthesis ofN-aryl amides. The present amination reaction of aryltriazenes with acetonitrile was carried out with acetonitrile as nitrogen donor, stable aryltriazenes as aryl precursors by the cleavage of Csingle bondN bond, water as oxygen source, and Brønsted acidic ionic liquids (BAILs) as potential promoter under ambient conditions. Remarkably, the practicality of this method was further proved through the reusability of the promoter BAILs. The environmentally benign nature, stable and readily available starting materials make the protocol more attractive for preparingN-aryl amides than traditional methods.
