Efficient grafting of redox-active ferrocene polymers from α,ω-diiodoalkanes at cathodically charged glassy carbon was written by Jouikov, Viatcheslav;Simonet, Jacques. And the article was included in Journal of Applied Electrochemistry in 2012.Reference of 6294-17-3 The following contents are mentioned in the article:
α,ω-Dihaloalkanes, when cathodically reduced at glassy carbon (GC), can be immobilized at the electrode surface. The present contribution focuses on the reduction of 1,8-diiodooctane, as model dihalo-substrate, in an aprotic organic solvent containing tetraalkylammonium salts as electrolyte. It is expected that these compounds in contact with GC, polarized at potentials more neg. than -1.7 V vs. Ag/AgCl, partly lead to monoiodoalkyl chain immobilization onto carbon. The process corresponds to the cathodic charge of graphitized and fullerenized zones present in carbon followed by a displacement reaction (analogous to a nucleophilic attack) towards pending C-I functions. This mode of grafting is then applied to the reaction of neg. charged carbon with bis-(ω-iodoalkyl)ferrocenes. Ferrocene is then used as an efficient redox probe. This study aims to point out the formation of a chem. grafted redox polymer at carbon electrodes that permits one to quantify the level of immobilized alkyl chains according to their chain length. Coverage levels were found to be high, and surface concentrations of ferrocene currently >10-8 mol cm-2 were reached. Ferrocene layers deposited onto carbon were found to be chem. and electrochem. stable and expected to be suitable for efficient electricity storage. This study involved multiple reactions and reactants, such as 1-Bromo-6-chlorohexane (cas: 6294-17-3Reference of 6294-17-3).
1-Bromo-6-chlorohexane (cas: 6294-17-3) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Reference of 6294-17-3
