Abstract

A possibility of using metal complexes with redox-active ligands in organic electrosynthesis is demonstrated on the basis of literature data analysis. Unlike homogeneous catalysis, many examples are known for the application of complexes of this type in electrocatalytic processes characterized by a higher selectivity and milder conditions. Interest in metal complexes with redox-active ligands is due to their use in the heterogeneous electrocatalysis as well. The main attention is given to advantages of the indirect electrosynthesis of organic compounds, in particular, sulfur derivatives, in the presence of mediators or electrocatalysts based on metal complexes with redox-active ligands. Active forms of metal complexes are generated at the electrodes and can initiate the further transformations of inert substrates. A significant decrease in power expenses compared to the direct redox activation of reagents is the main advantage of indirect electrosynthesis. The cyclic processes favoring a permanent regeneration of metal complexes lead to an increase in the yield of target compounds.

有机硫化合物间接电合成中氧化还原活性配体的金属配合物

摘要

根据文献数据分析，证明了在有机电合成中使用具有氧化还原活性配体的金属配合物的可能性。与均相催化不同，这种类型的配合物在电催化过程中的应用是已知的，其特征是更高的选择性和更温和的条件。人们对具有氧化还原活性配体的金属配合物的兴趣是由于它们在非均相电催化中的应用。主要关注的是在基于具有氧化还原活性配体的金属络合物的介体或电催化剂存在下间接电合成有机化合物，特别是硫衍生物的优点。金属络合物的活性形式在电极处产生，并且可以引发惰性基质的进一步转化。与试剂的直接氧化还原活化相比，电力费用的显着降低是间接电合成的主要优点。有利于金属配合物永久再生的循环过程导致目标化合物产量的增加。
