2,4-二羟基-5-乙酰苯乙酮缩水杨酰肼单Schiff碱及其配合物的合成

Synthesis of Transition Metal Complexes of 5-Acetyl-2,4-dihydroxyacetophenone Salicylhydrazone

以吡啶,DMF为溶剂,成功合成了未见文献报道的2,4-二羟基-5-乙酰苯乙酮缩水杨酰肼单Schiff碱(LH2)的过渡金属配合物[ML,M=Cu(Ⅱ),Zn(Ⅱ),Ni(Ⅱ)和Co(Ⅱ)],其结构经UV,1HNMR,IR,MS及元素分析表征。结果表明,Schiff碱是一种三齿配体,在配合物中溶剂分子参与了配位。

Four transition metal complexes[ ML, M = Cu（ Ⅱ）, Zn（ Ⅱ ）, Ni（ Ⅱ ） and Co（ Ⅱ ） ] of 5-acetyl-2,4-dihydroxyacetophenone salicylhydrazone（ single Schiff base, LH2 ） were synthesized in DMF and pyridine. The structures of LH2 and ML were confirmed by UV, 1H NMR, IR, MS and elemental analysis. The results showed that the Schiff base was a trident ligand and three pyridine molecules were found in the complexes.
