Oxidative coupling of 2-hydrazino-4,6-disubstituted 1,3,5-triazines with N,N-disubstituted anilines was studied. The oxidative coupling reaction proceeded by the use of potassium hexacyanoferrate(III) as the oxidizing agent in aqueous acetic acid solution buffered at pH 4.4 with sodium acetate at room temperature to give corresponding phenylazo-1,3,5-triazines in good yields.
研究了 2-肼基-4,6-二取代的 1,3,5-三嗪与 N,N-二取代苯胺的氧化偶联。氧化偶联反应通过使用六氰基高铁酸钾 (III) 作为氧化剂在乙酸水溶液中进行,乙酸水溶液在室温下用乙酸钠缓冲至 pH 4.4,以良好的收率得到相应的苯基偶氮-1,3,5-三嗪。
