Abstract

Organic electrosynthesis has become a green, efficient and sustainable alternative to traditional organic transformation for the redox reactions. In this connection, indirect electrolysis employing redox mediators is attaining increasing significance as it offers a chance to improve reaction selectivity and avoids the over-oxidation/reduction issues encountered in direct electrolysis. Triarylamines and triarylimidazoles, as representative organic molecular mediators, have attracted widespread attention in recent years due to the advantages of well-defined easy structural modification and tunable redox ability. Hence, in this minireview, the recent growth of triarylamine and triarylimidazole derivatives mediated electrochemical oxidation reactions were presented, highlighting the structural optimization, electrochemical performance and reaction mechanism of these organic mediators. Moreover, the photocatalytic and photoelectrocatalytic cases with these molecular mediators were also highlighted. To conclude, the current challenges and future prospects of this field are also discussed.

分子电（光）催化：有机电合成中由三芳基胺和三芳基咪唑衍生物介导的氧化体系

有机电合成已成为氧化还原反应中传统有机转化的一种绿色、高效和可持续的替代方法。在这方面，采用氧化还原介质的间接电解法越来越重要，因为它提供了一个提高反应选择性的机会，并避免了直接电解法中遇到的过度氧化/还原问题。近年来，三芳基胺和三芳基咪唑作为具有代表性的有机分子介质，因其易于结构修饰、氧化还原能力可调等优点而受到广泛关注。因此，本综述介绍了三芳基胺和三芳基咪唑衍生物介导的电化学氧化反应的最新进展，重点介绍了这些有机介质的结构优化、电化学性能和反应机理。此外，还重点介绍了这些分子介质的光催化和光电催化案例。最后，还讨论了该领域当前面临的挑战和未来前景。

期刊介绍： Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry. The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
