oxygen-transfer reactions proceed via 1:1 charge-transfer (CT) complexes formed between the substrates and cumylperoxyl radical. The primarykineticisotopeeffects are determined by comparing the rates of N,N-dimethylanilines and the corresponding N,N-bis(trideuteriomethyl)anilines. The isotope effect profiles are quite different from those reported for the P-450 model oxidation of the same series of substrates
Ionic liquids have been prepared from simple metallocenium cations and bis(trifluoromethanesulfonyl)amide anion (TFSA). Their properties were tunable by the choice of metals and substituents; the ferrocenium salts were deep-blue paramagnetic liquids, which are readily prepared by a one-step solventless reaction, and the cobaltocenium salts were orange diamagnetic liquids.

single-electron-transfer (SET) activation in the cleavage of cobalt–carbonbonds of alkylcobalt(III) complexes with iodine is shown by the identification of products that could arise only via an SET pathway as well as by the kinetic comparison between the cleavage reaction of alkylcobalt(III) complexes with iodine and the electron-transfer reaction of ferrocene derivatives with iodine in acetonitrile.
通过鉴定只能通过 SET 途径产生的产物以及动力学比较,证明了单电子转移 (SET) 活化在烷基钴 (III) 配合物与碘的钴-碳键断裂中烷基钴 (III) 配合物与碘的裂解反应与二茂铁衍生物与碘在乙腈中的电子转移反应之间的关系。
Ionic Conductivity Induced by Photooxidation of Ferrocene in Polymer Film Containing Organotin Compound
Ionic conductivity of poly(ethyl methacrylate) film containing photooxidizable dibutylferrocene and bromotributylstannane was induced by UV light irradiation in contact with the anion-conducting polymer film containing a cobaltocemum salt. The enhanced ionic conductivity decreased in the dark.
