Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method that can produce azo compounds at good yields by making oxygen or an oxygen-containing gas act on hydrazo groups of hydrazo compounds when oxidatively dehydrogenating them.SOLUTION: Azo compounds are produced by making oxygen or an oxygen-containing gas act on hydrazo compounds in the presence of vanadium or cerium compounds, and a solvent.SELECTED DRAWING: None 【課題】ヒドラゾ化合物のヒドラゾ基を酸化的に脱水素する際に、これに酸素もしくは酸素を含むガスを作用させることで収率良くアゾ化合物が製造できる方法を提供する。【解決手段】ヒドラゾ化合物に、バナジウム化合物またはセリウム化合物、および溶媒の存在下で、これに酸素もしくは酸素を含むガスを作用させることでアゾ化合物を製造する。【選択図】なし
