Redox-active ionic liquids (RAILs) are gaining attention as a material that can create a wide range of functions. We herein propose a charge-transfer (CT) RAIL by mixing two RAILs, specifically...
The relaxation time of several ferrocene derivatives was measured, and the internal rotation was discussed. For almost all the derivatives, the degree of the internal rotation was constant in spite of the different molecular weights. However, for (triphenylmethyl)ferrocene, the rotation of the unsubstituted ring would be slower due to the bulkiness of the substituent. Furthermore, the derivatives that have a hydroxyl-or acetyl group on the substituent were also discussed. Their rotation would be influenced by the location of these substituents.
Abstract:The oxidation reaction of ferrocene derivatives is important because of its biological applications. The reactivity is affected by metal ions. However, it is not clear how to interact the metal ions with the ferrocenes. In this paper, the oxidation reactivity of (o-acetylphenyl)ferrocene was investigated in the view of solvent effect and the addition effect of salicylic acid. Furthermore, the measurement of the relaxation time was carried out. As a result, Al 3+ would strongly interact with (o-acetylphenyl)ferrocene so that prevent the mobility of the acetyl group.
The reaction of (Me4N)4[Cd10S4(SPh)16] (1) with diphenyl diselenide (2) in propionitrile afforded a molecular cluster, (Me4N)4[Cd10S4(SePh)16] (3), the structure of which was determined by X-ray crystallography. Ligand exchange proceeded in a heterogeneous reaction system, and the use of a less polar solvent appeared to be crucial for the synthesis of 3 to prevent degradation of the Cd10S4Se16 cluster core.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
