	With hydrazine hydrate In chloroform at 20℃;	1.1; 2.1; 3.1 (1) Synthesis of ligand 3,5-dimethyl-4-(4'-pyridyl)-pyrazole (HL, C10H11N3) At -20°C, dissolve 36.5mL of 4-picoline (372 mmol) in 50mL of CHCl3, add 21.2mL of acetyl chloride (300 mmol) dropwise within 10-15min with a separatory funnel under stirring conditions , after stirring for 60min, the solution turns dark green, and the reaction is continued for 5h,A brownish-yellow liquid is obtained, and a brown solid is obtained by distillation under reduced pressure. After dissolving the solid solution in toluene, a yellow solution and a brown 4-picoline hydrochloride insoluble in toluene are obtained, and the 4-picoline hydrochloride is removed by suction filtration under reduced pressure. hydrochloride, the resulting filtrate was purified by thin-layer chromatography to obtain a yellow oily substance 3-(pyridin-4-yl)pentane-2,4-dione, which was added to 3-(pyridin-4-yl ) pentane-2,4-dione was added 6mL hydrazine hydrate for ring closure, stirred at room temperature for 17h, and the solvent was distilled off under reduced pressure to obtain a mixture of ligand HL and a small amount of impurities, and water was added to the resulting mixture (the ratio of solid to liquid was 1g : 325mL), recrystallized at -4°C to obtain colorless crystals, after drying (60°C, 5h), a white solid powder was obtained, which was the ligand 3,5-dimethyl-4-(4'-pyridine base)-pyrazole (HL).
