including textiles and fabrics, and can serve as ideal supports of heterogeneous palladium catalysts. An efficient strategy for the preparation of 2-(trifluoromethyl)quinazolin-4(3H)-ones via a three-component carbonylative reaction of trifluoroacetimidoyl chlorides and amines using a heterogeneous activated carbon fiber-supported palladium catalyst has been developed. In contrast to the homogeneous catalytic
活性碳纤维以其独特的物理和化学性质而闻名,越来越多地应用于纺织品和织物等多种行业,并且可以作为多相钯催化剂的理想载体。开发了一种使用非均相活性碳纤维负载钯催化剂,通过三氟乙酰亚胺酰氯和胺的三组分羰基化反应制备 2-(三氟甲基)喹唑啉-4(3H)-酮的有效策略。与之前报道的均相催化方案相比,观察到非均相反应的效率更高,并且 Pd/ACFs 催化剂可以循环使用五次,并且稳定性良好,催化反应活性略有下降。
