摘　　要：吡唑啉酮是化工合成的重要中间体.本文介绍了以2-乙酰基丁二酸二甲酯为原料,通过与2,4-二磺酸苯基重氮盐缩合成腙,然后碱性闭环制得最终产物.对此化合物的合成条件和影响因素进行讨论研究.Pyrazolone compounds are important organic synthesis intermediates. This paper describes the synthesis of hydrazone by reacting with dimethylacetyl succinate as raw material by reaction with 2,4-disulfbnic acid phenyldiazonium salt, followed by alkaline ring closure to obtain final product.The synthesis conditions and influencing factors of this compound are discussed.
