Heterogeneous electron-transfer kinetics of nitro compounds in room-temperature ionic liquids

Mass transport and heterogeneous electron transfer of a ferrocene derivative in a room-temperature ionic liquid

“…It has been reported that the long-term diffusive response in the dielectric spectrum reflect ion reorientation [26]. A marked decrease in the electron transfer rate constant was observed in the reduction of nitro-aromatic compounds in ionic liquids [52]. This change was attributed to the increase in the inner-sphere reorganization energy because of ion-pairing processes.…”

Preparation of Copper Nanoparticles and Catalytic Properties for the Reduction of Aromatic Nitro Compounds

“…1 In general, the amino aryl compounds can be obtained by the reduction of the nitro aryl compounds. There are several approaches to realize the reduction process: metal/acid reduction, 2,3 catalytic hydrogenation, 4-6 electrolytic reduction, 7 homogeneous catalytic transfer hydrogenation, 8 heterogeneous catalytic transfer hydrogenation, 9-13 etc. However, these methods have certain shortcomings:…”

Electrochemical Rate Constants in Room Temperature Ionic Liquids: The Oxidation of a Series of Ferrocene Derivatives

“…[9][10][11][12][13][14][15][16][17][18][19][20][21][22] Reports on more fundamental investigations such as the rate of heterogeneous electron transfer in this media have been less common. Hapiot and co-workers recently reported the heterogeneous rate constants for the reduction of a series of nitroaromatic and aliphatic compounds in 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)A C H T U N G T R E N N U N G imide and triethylbutylammonium bis(trifluoromethylsulfonyl)-imide [23] as well as for the oxidation of ferrocene in 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide. [16] Doherty and co-workers also measured the heterogeneous rate constants for the reduction of benzaldehyde in two different ionic liquids.…”
