两种新型光敏剂吖啶酮类化合物的合成

Synthesis of two new type photosensitive acridone compounds

以苯胺类化合物为原料 ,先后以邻氯苯甲酸和碘苯为烷基化试剂进行了N 烷基化反应 ,再用浓硫酸使其环化制得N 苯基吖啶酮和 3 乙氧基 N 苯基吖啶酮 ,并用红外光谱及质谱仪检测了各中间体及目标产物的结构。结果表明 ,当以对乙氧基苯胺为原料时 ,其第二步反应温度需比以苯胺为原料时降低 70～ 80℃才能得到目标产物 ;第三步 2 羧基 4′ 乙氧基三苯胺脱水环化生成了 3 乙氧基 N 苯基吖啶酮。

Aniline compounds are used as raw material and reacted with anthranilic acid and then phenyl iodide as alkylating agents to give alkylating products followed by cyclizing with concentrated sulphuric acid to give a N phenyl acridone(or 3 ethoxyl N phenylacridone).The structure of intermediate and target compound are determined by IR and MS.The results show that using p ethoxylaniline instead of aniline in the second step reaction, the reaction leads to lower temperature 70～80 ℃ to give target compound.In the third step, dehydrating cyclization of 2 carboxyl 4′ ethoxyltriphenyl amine results in 3 ethoxyl N phenylacridone.
