Electrochemical Reduction of Benzyl Chloride on Silver, Graphite and Silver/Graphite Powder Macroelectrodes

Carbon Nanotube/Graphite Mixtures Used as Cavity Cell Macroelectrodes and their Unexpected Behavior Towards Benzyl Bromide Electroreduction

“…Depending on reaction conditions (solvent, electrolyte and electrode material) the first electron transfer (Eq. 1) can be kinetically favored, and a positive potential shift can be observed for the radical formation step ,. Since the [PhCH 2 ]⋅ electrode desorption step is necessary for DPE formation (Eqs.…”

“…Previous works carried out on silver surface demonstrated that adsorption processes and the reaction medium strongly influence the products. These works also showed that less cathodic potentials favor DPE formation ,,,. Therefore, the reaction pathway for the systems studied here depend on the adsorptive processes as well as on the applied potential.…”

“…For instance, benzyl bromide was electro‐reduced in droplets/aqueous and hexane/butanol/water microemulsion electrolytes, indicating the formation of the benzyl radical as intermediate. In other studies, the electrochemical reduction of benzyl halides was carried out in electrochemical cavity cell in the absence and presence of solvent (N−N‐dimethyformamide), and different electrode materials: graphite and silver doped graphite, or silver/graphite composite powders ,…”

“…The development of sustainable synthetic methodologies for decreasing or eliminating the use of organic solvents and organometallic by‐products (green chemistry), and the better understanding of the reaction mechanisms on the electrode interface have motivated these investigations …”

Synthesis of Ag nanoparticles/ordered mesoporous carbon as a highly efficient catalyst for the electroreduction of benzyl bromide

“…However, the yield was only 46%. 16 De Souza et al [17][18][19][20] obtained the best yield for bibenzyl production (89%) on Ag/graphite powder macroelectrodes by examining the catalytic properties of various powder macroelectrodes; however, the reaction device was complicated. Thus, a new method for preparing effective electrodes with high activity, selectivity, and stability for the electrocatalytic reduction of C-X bonds is required.…”
