摘要过渡金属有机金属化合物的两个基本方面是（i）它们在金属上经历有机和无机物种转化的能力和（ii）由金属引起的氧化还原变化的容易性。这篇评论指出了这第二个方面的潜力，以及如何设计有机金属化合物并用于促进电子转移（ET）。廉价易得的有机金属电子库可以方便地实现各种化学计量和催化ET过程。在化学计量反应中，盐效应和分子氧的活化是我们特别关注的问题。催化ET涉及电化学反应的氧化还原催化（催化剂降低过电位）和有机金属反应的电催化（配体取代、解络合、异构化、螯合、插入）。这些过程可以使用（而不是电极）铁三明治化合物：缺电子铁Cp2Fe+（17价电子）的氧化物。
Abstract Two essential facets of transition metal organometallic compounds are (i) their ability to undergo transformations of organic and inorganic species at the metal and (ii) the ease of redox changes induced by the metal. This Comment indicates the potential of this second aspect and how organometallics may be designed and used to promote electron transfer (ET). Inexpensive, easily available organometallic electron-reservoirs can conveniently effect a variety of stoichiometric and catalytic ET processes. The salt effect and the activation of dioxygen are especially under our scrutiny in stoichiometric reactions. Catalytic ET involves redox catalysis of electrochemical reactions (the catalyst lowers the overpotential) and electro-catalysis of organometallic reactions (ligand substitution, decomplexation, isomerization, chelation, insertion). These processes can be effected using (instead of an electrode) iron sandwich compounds: the electron-deficient ferricinium Cp2Fe+ (17 valence electrons) for oxid...
