苯并咪唑衍生物的合成及表征

摘要

氧气作为氧化剂，邻苯二胺与芳醛为原料，甲醇为溶剂，反应合成了2种苯并咪唑类衍生物：2-(4-甲基苯基)苯并咪唑，2-(4-溴苯基)苯并咪唑，应用傅里叶红外光谱仪、核磁共振仪和元素分析仪分析和表征了目标化合物的结构。%Oxygen as the oxidant, two benzimidazole derivatives were synthesized with aromatic aldehydes and 1,2-diaminobenzene as raw materials in methanol. Two kinds of benzimidazole derivatives were 2-(4-methylphenyl)benzimidazole and 2-(4-bromophenyl)-benzimidazole. The product was characterized by FTIR, 1H-NMR and elemental analysis.
