一种类芳香性金属配合物的亲电取代反应研究

Studies on electrophilic substitution of a quasi aromatic Ni(Ⅱ) complexes

合成了一种不对称类芳香性Ｎｉ（ Ⅱ） 金属有机配合物，通过芳酰化试剂对配合物中Ｎｉ（ Ⅱ） 离子对位具有富电子性的次甲基的亲电取代反应性研究，获得了５ 个新的芳酰化金属有机配合物，并用元素分析及其它光谱分析手段进行了表征．亲电取代反应的发生说明了这类金属配合物具有类芳香性，并为改善其光、电性能提供了良好的途径．

A asymmetric quasi aromatic Ni(Ⅱ)?complexes has been prepared.Electron rich of methine carbon atom in Ni heterocycle enables typical electrophilic substitution reaction with different p substituents aroylating agents.Five aroylated Ni(Ⅱ)complexes have been prepared and characterized by elemental analysis and spectral analysis. A good proof of quasi aromaticity and a promising approach for improving their photo electronic functions is given.
