The cyclic voltammetric behavior of [FeIIICl(salen)] complexes has been investigated in CH3CN and compared to that obtained with [CoII(salen)] analogues. Details of the mechanism associated with iron- and cobalt-salen complex reduction in the presence of the lithium cation have been elucidated by comparison of simulated and experimental voltammograms. Electrogenerated [FeICl(salen)]²⁻ and [FeICl(salophen)]²⁻ complexes catalyze the dehalogenation of halo-alkyl compounds as is the case with [CoI(salen)]⁻ complexes, even in the presence of the lithium cation which allows the reduction to occur at a less negative potential.
[FeIIICl(salen)] 配合物在 CH3CN 中的循环伏安行为已被研究，并与 [CoII(salen)] 类似物的行为进行了比较。通过比较模拟和实验伏安图，阐明了与铁和钴-salen 配合物在锂离子存在下还原相关的机理细节。电生成的 [FeICl(salen)]²⁻和 [FeICl(salophen)]²⁻配合物可催化卤代烷基化合物脱卤，就像 [CoI(salen)]⁻配合物一样，即使在锂离子存在下也能在更负的电位下发生还原。
