合成了四个含氟苯并咪唑衍生物 ,并用红外光谱进行了表征 .探讨了合成该化合物的条件和方法 .结果表明 ,邻苯二胺与芳香酸反应用无水吡啶做溶剂、三氯氧磷作缩合剂以及与醛反应用甲醇作溶剂、铁氰化钾作氧化剂可得较高产率 Four fluorine-containing benzimidazole derivatives were synthesized and characterized by FTIR. The conditions and methods for the synthesis of the compound were discussed. The results showed that the reaction of o-phenylenediamine with aromatic acid was performed with anhydrous pyridine as solvent, Phosphorus as a condensing agent and the reaction with aldehyde with methanol as a solvent, potassium ferricyanide as oxidant can be a higher yield
