摘　　要：利用1-苯基-3-甲基-5-吡唑啉酮与苯甲酰氯进行酰化反应生成1-苯基-3-甲基-4-苯甲酰基-5-吡唑啉酮(PMBP),然后以PMBP为本体分别与正丁基胺、对碘苯胺、N,N-二甲基乙二胺进行缩合反应得到的PMBP缩正丁胺、PMBP缩对碘苯胺、PMBP缩N,N-二甲基乙二胺三种物质,并且对于得到的三种目标产物进行红外、紫外和晶体结构的表征,通过分析和研究结果证明此次合成的物质就是目标产物,为以后对于β-二酮类席夫碱及其配合物进行深入科学研究和应用提供良好的基础和理论依据。In this paper,1-phenyl-3-methyl-5-pyrazolone was acylated with benzoyl chloride to form 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone(PMBP).Then PMBP was condensed with n-butylamine,p-iodoaniline,N,N-dimethylethylenediamine to form PMBP n-butylamine,PMBP p-iodoaniline and PMBP n-butylamine,Three substances of n-dimethylethylenediamine were characterized by IR,UV and crystal structure.Through analysis and research results,it was proved that the synthesized substance was the target product,which provided a good basis and theoretical basis for further scientific research and application ofβ-diketone Schiff bases and their complexes..
