摘　　要：合成新型酰基吡唑啉酮化合物及其金属配合物,研究其热稳定性。在非水溶剂中,对硝基苯肼与乙酰乙酸乙酯反应制得酰基吡唑啉酮。通过回流新配体和金属醋酸盐合成了配合物。合成了新β-双酮试剂,1-对硝基苯基-3-甲基-4-(α-呋喃甲酰基)吡唑啉酮-5(HL)及其锌和镍的配合物。元素分析及摩尔电导值表明配合物的组成为[NiL2]·2C2H5OH·[ZnL2]·2C2H5OH。通过红外光谱、紫外光谱、差热—热重分析对配合物进行了表征。结果表明配合物的中心离子均为4配位。它们加热至185℃分解。A new acylpyrazolone compound and its metal complexes are synthesized in this research work.Their thermo-stability was studied.In non-aqueous solvent,acylpyrazolone was prepared by a reaction of p-nitrophenyl hydrazine and acetylacetic ether and its complexes were obtained from refluxing a solution of new ligands and metal acetate.Aβ-diketone compound,1-(p-nitrophenyl)-3-methyl-4-(α-furoyl) pyrozolone-5(HL) and its zinc and nickel complexes were synthesized.Elemental analysis and value of molar conductance showed that the general formula of the complexes are ·2C_2H_5OH and ·C_2H_5OH.They were characterized with IR,UV-visible and TG-DTA.The results indicated that the complexes were all of quadridentate.They would be decomposed at 185℃.
