二茂铁席夫碱类衍生物的合成

Synthesis of Ferrocenyl Schiff bases derivatives

摘要:

以二茂铁，取代胺为原料，经甲酰化、缩合反应，合成了七个具有大π共轭体系的二茂铁席夫碱有机金属三阶非线性光学材料。分析合成反应过程，优化反应条件，得出以碱性Al2O3为催化剂，在回流温度下，以二甲苯为溶剂，产物收率为59.1%。比较了不同的取代胺对反应收率的影响，得出胺的碱性越强，反应收率越高。所有化合物均由核磁共振（1HNMR）、紫外（UV）、质谱(MS)等表征了结构。方法简单、可行。

Abstract:

Seven ferrocenyl schiff base organometallic compounds with third-order nonlinear optical properties which had large π-conjugated systems were designed and synthesized starting from ferrocene and substitutional amine. The process of reactions were discussed and the conditions of the reactions were selected. The results showed that the optimal parameters were as follows: catalyst alkaline Al2O3, solvent xylene, reflux 10 h. The yield was 59.1% .The influence of different substituted amine on the reaction yield was compared. It was concluded that the amine with more intense basicity give the higher yield. All the compounds were characterized by 1H NMR，MS and UV．The synthetic methods were simple and feasible.
