摘　　要：以N-烃基咔唑为原料,经Friedel-Crafts酰化、成肟和酯化反应,合成了6种咔唑肟酯衍生物。通过正交设计实验,探讨了产物1-[3’-(6’-苯甲酰基-N-乙基咔唑)]-1-丁酮肟-O-乙酸酯的Friedel-Crafts酰化的最佳反应条件:N-乙基咔唑为0.02 mol时,反应物苯甲酰氯与N-乙基咔唑摩尔配比为1∶1.2,催化剂A lC l3与N-乙基咔唑摩尔配比为1∶1.2,25℃下反应3.5 h,产率可达94.6%。利用1HNMR,IR,UV和元素分析对目标产物进行了结构表征。并进行了光引发性能测试。Six carbazole oxime ester derivatives were synthesized through Friedel-Crafts acylation,oximation and esterification from N-alkyl-carbazole.The optimal operation condition of Friedel-Crafts acylation for the product I was determined by orthogonal experiment: 0.02 mol N-ethyl-carbazol,n(benzoic cloride) /n(N-ethyl-carbazol)=1∶1.2,nAlCl3/n(N-ethyl-carbazol) =1∶1.2,at 25 ℃ for 3.5 h.The yield was 94.6%.The structure of the target compounds was characterized by 1HNMR,IR,UV and elemental analysis.Photoinitiativi...
