In this paper 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 product Ⅰ was determined by orthogonal experiment: 0.02mol N-ethyl- carbazol, n Benzoyl chloride/n N-ethyl- carbazol=1.2, n AlCl3/n N-ethyl- carbazol=1.2 , at 25 oC for 3.5h. The yield was 94.6%. The structure of the target compounds was characterized by 1HNMR, IR ,UV and elemental analysis. Photoinitiativity of the products was studied .
