Abstract Hydrazonoyl chlorides 1 reacted with 2-aryl-1-cyano-1-thiazol-2-ylethenes 2 in presence of triethyl-amine to give the cycloadducts 4. which were converted to the corresponding pyrazoles 5 by the action of sodium methoxide. The reaction of hydrazonoyl halides 1 and 6 with each of 2-aryli-dene-2-cyanoethanethioamides 7 and 2-arylhydrazono-2-cyanoethanethioamides 14 in ethanolic tri-ethylamine
摘要 在三乙胺的存在下,腙酰氯 1 与 2-芳基-1-氰基-1-噻唑-2-亚乙基 2 反应生成环加合物 4,在甲醇钠的作用下将其转化为相应的吡唑 5。已经研究了腙酰卤 1 和 6 与 2-芳基-dene-2-氰基乙硫酰胺 7 和 2-芳基腙-2-氰基乙硫酰胺 14 在乙醇三乙胺或氢氧化钠乙醇溶液中的反应。所有产品的结构都是基于它们的光谱数据和替代合成建立的。
