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。
Synthesis of novel acylpyrazolone compounds and their metal complexes, to study the thermal stability. In non-aqueous solvents, p-nitrophenyl hydrazine and ethyl acetoacetate reaction acyl pyrazolone. The complex was synthesized by refluxing the new ligand with metal acetate. A new β-diketone reagent, 1-p-nitrophenyl-3-methyl-4- (α-furoyl) pyrazolone-5 (HL) and its zinc and nickel complexes were synthesized. Elemental analysis and molar conductivity showed that the composition of the complex was [NiL2] · 2C2H5OH · [ZnL2] · 2C2H5OH. The complexes were characterized by IR, UV and DTA-TG. The results show that the complex center ions are 4 coordination. They heat to 185 ° C to decompose.
