Cyanobenzoic acids proved to be suitable starting materials for the transformation into multifunctional products of the 4H-imidazole type. Employing two different pathways, the new derivatives 1b-d which possess carboxy/cyano groups were synthesized. In addition, derivative 1d formed the basis for the construction of novel bis-4H-imidazoles with two different complexation spheres. The structures of
氰基苯甲酸被证明是转化为 4H-咪唑型多功能产品的合适起始原料。采用两种不同的途径,合成了具有羧基/氰基的新衍生物 1b-d。此外,衍生物 1d 是构建具有两种不同络合球体的新型双 4H-咪唑的基础。所有新衍生物的结构均通过核磁共振光谱、质谱、元素分析、紫外/可见/荧光光谱和电化学测量证实。图形摘要羧基和氰基取代的 4H-咪唑的合成:氧化还原活性配体作为金属-金属多键化合物和异双金属配合物的起始材料
