摘　　要：以N-烯丙基咔唑为原料,经Friedel-Crafts酰化反应、成肟和酯化,得到目标化合物。通过正交试验研究了关键步骤Fridel-Crafts酰化,得到最佳反应条件:N-烯丙基咔唑用量为0.020mol,催化剂与原料摩尔比1.10,反应物摩尔比1.15,25℃下反应4h,产率可达94.2%。目标产物的结构通过IR、UV、1HNMR和元素分析测试技术进行表征,并与商品IrgOXE-2的光引发性能进行了比较。1-（ 6-Benzoyl-9-allyl-9. H.- carbazol-3-yl）-butane-l-one oxime O-ethyrate was synthesed by Friedel-Crafts acylation, oximation and esterifieation from N-allylcarbazole. As the key step of the synthesis, the optimal operation of Friedel-Crafts acylation was established by orthogonal experiment. For the 0. 02 mol N-allylcarbazole, molar ratio of catalyst to reactants n （AICl3 ）/n （N-allylcarbazole） was 1.10, molar ratio of reactants n（ benzoic eloride ）/n（ N-allylcarbazole ） was 1.15, and the reaction was carried out at 25 ℃ for 3 h. The average yield was 94. 2%. The structure of the target compound was characterized by 1H NMR, UV, IR and elemental analysis. Photoinitiability of the compound was investigated comparing with the commercial product.
