Generally applicable, palladium-catalyzed direct arylations of 1,2,3-triazoles with aryl chlorides were accomplished through conventional heating at reaction temperatures of 105–120 °C. Thereby, intra- and intermolecular CH bond functionalizations were achieved with a variety of differently substituted chlorides as electrophiles, bearing numerous valuable functional groups.
通常适用的是,通过在105-120°C的反应温度下进行常规加热来实现1,2,3-三唑与芳基氯化物的钯催化直接芳基化。因此,用各种不同取代的氯化物作为亲电子体,实现了分子内和分子间的CH键官能化,并带有许多有价值的官能团。
