摘要

我们设计并合成了四铁二茂基低硫噻吩，即4,4 ' 5,5 ' -四铁二茂基-2,2 ' -双噻吩(TFBT)和4,4″，5,5″-四铁二茂基-2,2 ':5 '，2″-噻吩(TFTT)。通过电化学技术，我们发现四铁二茂基低硫噻吩由四个二茂铁片段和一个α-低硫噻吩间隔剂引发多重氧化还原反应，并且α-低硫噻吩间隔剂中的多个噻吩环可以调谐到氧化还原电位和多重电子转移过程中。因此，我们通过构建4个具有有机金属氧化还原活性的二茂铁和1个具有有机氧化还原活性的α-寡硫吩，成功地构建了不同类型的多步多电子氧化还原体系。

Electrochemical studies of the multi-step multi-electron redox process of tetraferrocenyloligothiophenes with electron donor and acceptor abilities

We have designed and synthesized tetraferrocenyloligothiophenes, namely, 4,4′5,5′-tetraferrocenyl-2,2′-bithiophene (TFBT) and 4,4″,5,5″-tetraferrocenyl-2,2′:5′,2″-terthiophene (TFTT). By using an electrochemical technique, we revealed that tetraferrocenyloligothiophenes show multi-redox reactions derived from four ferrocene fragments and one α-oligothiophene spacer, and a number of the thiophene rings in the α-oligothiophene spacer can be attuned to the redox potentials and the multiple electron transfer process. Consequently, we have succeeded in the construction of different types of multi-step multi-electron redox systems by constructing four organometallic redox-active ferrocenes and one organic redox-active α-oligothiophene differing in the number of thiophene rings.

期刊介绍： Heteroatom Chemistry brings together a broad, interdisciplinary group of chemists who work with compounds containing main-group elements of groups 13 through 17 of the Periodic Table, and certain other related elements. The fundamental reactivity under investigation should, in all cases, be concentrated about the heteroatoms. It does not matter whether the compounds being studied are acyclic or cyclic; saturated or unsaturated; monomeric, polymeric or solid state in nature; inorganic, organic, or naturally occurring, so long as the heteroatom is playing an essential role. Computational, experimental, and combined studies are equally welcome. Subject areas include (but are by no means limited to): -Reactivity about heteroatoms for accessing new products or synthetic pathways -Unusual valency main-group element compounds and their properties -Highly strained (e.g. bridged) main-group element compounds and their properties -Photochemical or thermal cleavage of heteroatom bonds and the resulting reactivity -Uncommon and structurally interesting heteroatom-containing species (including those containing multiple bonds and catenation) -Stereochemistry of compounds due to the presence of heteroatoms -Neighboring group effects of heteroatoms on the properties of compounds -Main-group element compounds as analogues of transition metal compounds -Variations and new results from established and named reactions (including Wittig, Kabachnik–Fields, Pudovik, Arbuzov, Hirao, and Mitsunobu) -Catalysis and green syntheses enabled by heteroatoms and their chemistry -Applications of compounds where the heteroatom plays a critical role. In addition to original research articles on heteroatom chemistry, the journal welcomes focused review articles that examine the state of the art, identify emerging trends, and suggest future directions for developing fields.
