A simple, mild, and efficient synthesis of symmetric 3,6‐diarylpyridazine derivatives using a green catalytic one‐pot two‐step reaction of aryl methyl ketones, arylglyoxal monohydrates, and hydrazine hydrate was developed. Environmentally benign nature, high atom‐economy, no harmful byproduct, easy workup procedure, no column chromatography steps, and moderate to excellent yields of the products are
利用芳基甲基酮,芳基乙二醛一水合物和水合肼的绿色催化一锅两步反应,开发了一种简单,温和有效的对称3,6-二芳基哒嗪衍生物的合成方法。这种基于多组分的新方法的主要特点是环境友好,原子经济性高,无有害副产物,易于处理,无柱色谱步骤以及产品收率中等至优异。
