乙酰基二茂铁和二乙酰基二茂铁都很容易与过量的肼反应，得到相应的腙化合物。然后这些化合物可以通过金属介导的Schiff碱反应与Re（CO）（3）连接，产生一系列具有不同化学计量的二茂铁-Re（CO）（3）缀合物。具有1：1、1：2和2：1二茂铁：Re（CO）（3）比率的共轭物可以经由这种“模块化”类型的合成方法产生。这些共轭物的几个例子进行了结构表征，并研究了它们的光谱，电化学和光谱电化学行为。这些化合物的电子结构也探测使用DFT和TDDFT计算。(C)2016年爱思唯尔B。V.保留所有权利。
Acetyl ferrocene and diacetyl ferrocene both readily react with an excess of hydrazine to afford the corresponding hydrazone compounds. These compounds can then be linked to Re(CO)(3) via a metal-mediated Schiff base reaction, resulting in a series of ferrocene-Re(CO)(3) conjugates with different stoichiometries. Conjugates with 1:1, 1:2, and 2:1 ferrocene: Re(CO)(3) ratios can be produced via this "modular" type synthesis approach. Several examples of these conjugates were structurally characterized, and their spectroscopic, electrochemical, and spectroelectrochemical behaviors were investigated. The electronic structures of these compounds were also probed using DFT and TDDFT calculations. (C) 2016 Elsevier B. V. All rights reserved.
