3-氯苯甲醛丙氨酸席夫碱及其3d-过渡金属配合物的研究

Studies on a Schiff base derived from 3-chlorobenzaldehyde and alanine and its complexes of 3d-transition metals

合成了 3-氯苯甲醛丙氨酸席夫碱及其与Cu(Ⅱ ) ,Ni(Ⅱ ) ,Co(Ⅱ ) ,Zn(Ⅱ )离子所形成的配合物 ;以元素分析、摩尔电导、热重、红外光谱、1 HNMR谱等手段研究了化合物的组成和配位环境 ;对所合成的化合物进行了抑制超氧自由基的初步实验 ,发现 3-CACu、3-CANi有较强的抑制超氧离子自由基的作用 ,但与SOD相比相差较远 ,其余化合物几乎没有作用 .

Copper(Ⅱ),nickle(Ⅱ),cobalt(Ⅱ),zinc(Ⅱ)complexes with the Schiff base deried from 3-chlorobenzadehyde and alanine were synthesized.These compounds were charaterized by elemental analysis,IR, 1HNMR,TG-DTA and UV-Vis spectra.The free radical inhibition rate to O - 2 was also observed.The similarity of this series with 2-CA series was obviously.
