Cu(I)-catalyzed synthesis of di- and trisubstituted 1,3,5-triazine derivatives from dichlorotriazinyl benzenesulfonamide and corresponding nucleophiles is reported. Cations Cu(I) supported on macroporous and weakly acidic, low-cost industrial resin of polyacrylate type were used as a catalyst. The reaction times and yields were compared with traditional synthetic methods for synthesis of substituted
报道了一种有效且简单的方法,用于 Ullmann Cu(I) 催化从二氯三嗪基苯磺酰胺和相应的亲核试剂合成二和三取代的 1,3,5-三嗪衍生物。负载在大孔和弱酸性、低成本聚丙烯酸酯类工业树脂上的阳离子 Cu(I) 用作催化剂。将反应时间和产率与通过氯原子在二氯三嗪基苯磺酰胺中的亲核取代合成取代的 1,3,5-三嗪衍生物的传统合成方法进行了比较。发现 Ullmann 型反应显着缩短了反应时间,并且在某些情况下还提供了更高的产率。最后,通过 Ullmann 型反应在一锅合成设计中有效地制备了三取代的 s-三嗪衍生物。
