Abstract: In this paper 1-(6-benzoyl-9-allyl-9.H.-carbazol-3-yl)-butane-1-one oxime O-ethyrate was synthesed by Friedel-Crafts acylation, oximation and esterification from N-allylcarbazole. As the key step of the synthesis, the Friedel-Crafts acylation was researched. The optimal operation conditions were dertermined by orthogonal experiment: 0.02mol N-allylcarbazol, mol ratio of catalyst (nAlCl3/nN-烯丙基咔唑)1.10, mol ratio of reactants(n苯甲酰氯/nN-烯丙基咔唑)1.15,for 3h at 25℃. The average yield was 94.2%. The structure of the target compound was characterized by 1HNMR, UV, IR and elemental analysis.Photoinitiability of the compound was investigated.

Key words: carbazol oxime ester, synthesis, orthogonal experiment, photoinitiability
