Oxygen as an Oxidizing Agent in Electrocatalytic Oxidation of β-Dicarbonylic Compounds Using CeIV as a Mediator

Indirect Electrochemical Oxidation of p-Methoxy-Toluene to p-Methoxy-Benzaldehyde Using Ceric Methanesulphonate: A Scale-up Study

“…The use of the ceric ion as oxidant in organic chemistry is well-known, in chemical literature with numerous applications, for the oxidation of side chain methyl groups to aldehyde groups in polycyclic aromatic hydrocarbons. The mediated electrochemical oxidation (MEO) process with cerium ions is also involved in the electrosynthesis process for the production of several carbonyl compounds commercially and for the destruction of various organic pollutants. – Industrial applications of this oxidation process however are very limited, because of the high cost of the reagent and difficulties in disposing the effluent. Indirect oxidations using ceric ion have hence been widely studied for the oxidation of organic compounds, since the ceric ions in this process are electrochemically regenerated and recycled.…”

Influence of Ce(IV) ions amount on the electrochemical behavior of hybrid films in 0.1 mol L-1 NaCl solution

“…In previous works 10,21,22,28 , it has been reported that the addition of Ce 4+ ions to the hydrolysis solution provides an increase of the silanol groups condensation rate to form a denser and cross-linked coating. In addition, in organic chemistry, these ions are often used for the oxidation of alcohols [15][16][17][18]29,30 . The proposed general mechanism for such reaction shows that Ce 4+ ions form complexes with the ethanol molecules, which, when decomposed, form free radicals that react with each other leading to the polymerization of ethanol and / or silanol by a polymerization redox reaction 16,19 .…”

“…The use of ceric sulfate, in the modification of polymers and organic-inorganic hybrid materials by redox polymerization reaction is a widely used method with industrial importance [11][12][13][14][15][16] . For organic-inorganic hybrid materials, it is proposed that silanol molecules (R1-Si-(OH)3) and alcohol from the hydrolyzed precursors can complex with Ce 4+ ions to produce free radicals, thus increasing the polymerization and the polycondensation degree of the siloxane (Si-O-Si) network [17][18][19][20][21][22] .…”
