摘　　要：以苯偶姻和邻苯二胺为原料,SBA/NiCl2为催化剂,在超声条件下合成了喹喔啉衍生物,其结构经1H NMR和IR确证。考察催化剂类型、原料摩尔比和催化剂的用量对产率的影响。在最佳条件(苯偶姻和邻苯二胺物质的量比为1.0/1.0,催化剂用量为苯偶姻的10 mmol%,于70℃超声反应5 min)下,产率可达94.7%。Several quinoxaline derivatives were synthesized under ultrasonic conditions using benzoin and o-phenylenediamine as raw materials and SBA/NiCl2 as catalyst.The structures were confirmed by 1H NMR and IR.The effects of catalyst type,molar ratio of raw materials and amount of catalyst on the yield were investigated.The optimal conditions were as follows:the molar ratio of benzoin and o-phenylenediamine was 1.0/1.0,the amount of catalyst was 10 mmol%,and the ultrasound was applied at 70℃for 5 min.The yield was 94.7%.
