【摘要】 过渡金属有机配合物具有光、电、磁、催化、生物化学特性等特殊功能。电化学方法合成金属配合物,是以惰性电极或金属电极为阴极,以欲合成金属配合物的金属为“牺牲”阳极,在电解液中加入少量导电盐,通电流使阳极溶解,阴极发生还原反应合成金属配合物。电合成法具有反应选择性较高、产品纯度高、一步合成和环境污染少等优点,因此此方法在实际应用中有很广泛的应用前景。电化学合成法是一种可持续发展的绿色化学方法。近年来,电化学合成金属有机化合物的研究发展迅速。本论文主要研究如下:第一部分:水杨醛缩L-异亮氨基酸Schiff碱过渡金属Cu(II)、Zn(II)、Ni(II)配合物的电化学合成及表征。采用金属Cu、Zn、Ni为“牺牲阳极”,在无隔膜电解槽和含配体水杨醛缩L-异亮氨基酸Schiff碱的乙腈溶液中电解合成了Cu(II)、Zn(II)、Ni(II)配合物。利用元素分析、红外光谱、紫外光谱、热分析对配合物进行了表征,确定了配合物的化学组成为ML.nH2O(L=C13H15NO3, M= Cu(II)、Zn(II)、Ni(II), n=1,1,2),同时测定了Cu(II)配合物的电化学性质和金属电极在电解质中的电化学行为,Cu(II)L/Cu(I)L电对的可逆半波电位Er1/2为-0.79 V。第二部分:水杨醛缩甘氨酸、L-苯丙氨基酸Schiff-base混配Cu(II)、Zn(II)、Ni(II)金属配合物的电化学合成及表征。在以水杨醛缩甘氨酸Schiff-base的非水溶液中加入2-氨基吡啶为电解液,用Cu、Zn金属作阳极。和在以水杨醛缩L-苯丙氨基酸Schiff-base的非水溶液中加入2,2-联吡啶为电解液,用Ni金更多还原

【Abstract】 The transition metal organic complex exhibit function of the light, the electricity, the magnetism, the catalysis, the biochemistry characteristic and so on.The electrosynthesis of metal complexes use pure metal as sacrificing anode and inertia electrode or metal electrode as cathode.Current was passed through the electrolyte solution with supporting electro-condutive additives,Metallic anode was dissolved and reducing reaction occurred on cathode. The main advantage of electrochemical syntheses is that the reaction takes place in one step with high selective , high purity , non-pollution and so on. So the result is especially interesting since they show the possibility of wider application of electrosynthesis in the modern coordination chemistry.Electrosynthesis method is a green chemistry method with sustainable development. The development of electrochemical syntheses in syntheses of transition organometallics was very quick in recent years. In this paper,the main study obtained are as follows:Part one: Electrochemical Synthesis and Characterization of Transition Metal Cu(II)、Zn(II)、Ni(II) Complexes with a Schiff Base Ligand from Salicylidene and L-isoleucine.The direct electrosynthesis of Cu(II)、Zn(II) and Ni(II) complexes of salicylideneamino acid was accomplished by electrochemical dissolution of sacrificial metallic anodes in an acetonitrile solution of the ligand更多还原
