copper-catalyzed multicomponent reaction was developed for the synthesis of (arylselanyl)- or (arylsulfenyl)-alkyl-1,2,3-triazolo-1,3,6-triazonines. The products were obtained in moderate to excellent yields via the reaction of o-phenylenediamine, 2-azidobenzaldehyde and different arylchalcogenyl alkynes using catalytic copper iodide in 1,4-dioxane at 100 °C. The reactions tolerated a range of substituents
开发了一种有效的铜催化的多组分反应,用于合成(芳基硒基)-或(芳基亚磺酰基)-烷基-1,2,3-三唑-1,3,6-三嗪酮。通过在100°C下于1,4-二恶烷中使用催化碘化铜,使邻苯二胺,2-叠氮苯甲醛和不同的芳硫族炔基炔烃反应,以中等至极好的收率获得产物。该反应可耐受芳基硫属酰基炔烃上的一系列取代基,并被证明是组合合成新的硒或含硫三氮嗪衍生物的有效方法。
