potassium chlorate, sulfuric acid and ferrous sulfate as a catalytic oxidation system to oxidize the aryl substituted semicarbazide to prepare azo compounds in one phase have been described first time in this paper. Fourteen azo compounds have been synthesized in excellent yields(>90%). This method only needs cheap reagents, simple instrument and short reaction time. A possible mechanism has been suggested
摘要 本文首次描述了以氯酸钾、硫酸和硫酸亚铁为催化氧化体系,氧化芳基取代氨基脲单相制备偶氮化合物。已经以极好的收率(> 90%)合成了十四种偶氮化合物。该方法只需要便宜的试剂,仪器简单,反应时间短。已经提出了一种可能的机制。
