Electrooxidation of 2-arylfurans

Collection of Czechoslovak Chemical Communications, 1981
Electrochemical methoxylation of 2-phenylfuran (I) and 2-(4-nitrophenyl)furan (VI) proceeded anomalously, affording 5-methoxy-2-phenylfuran (XI) and 5-methoxy-2-(4-nitrophenyl)furan (XIII), respectively. 2-Phenyl-5-methylfuran (II) and methyl-2-(2-methylphenyl)-3-furoate (VIII) behaved normally giving the respective 2,5-dimethoxy-2,5-dihydrofuran ...

Glycerol Electrooxidation in Flow Reactors

ECS Meeting Abstracts, 2023
Transitioning away from fossil-fuel-based chemical manufacturing is critical in advancing towards a carbon-neutral society. Chemical manufacturing processes that can be driven by renewable energy and use renewable feeds or waste products from other processes are of particular interest.

Electrooxidation of N-methylindole

Journal of the Chemical Society, Faraday Transactions, 1998
The electrooxidation of N-methylindole (1-methylindole) results in the formation of soluble oligomers. Fluorescence spectroscopy and mass spectrometry indicate that the major product of this reaction is an asymmetric cyclic trimer, which is also shown to undergo a reversible one-electron redox reaction.

Electrooxidation of tigogenin acetate

Journal of Electroanalytical Chemistry, 2007
Electrooxidation of tigogenin acetate afforded two products: 3b-acetoxy-16b-hydroxy-23,24-dinor-5a-cholanoic acid lactone (2) and 20-epitigogenin acetate (3). The structure of the latter compound was confirmed by an X-ray analysis. The tentative mechanism of reac- tion is proposed. 2007 Elsevier B.V. All rights reserved.

Electrooxidative Dearomatization of Inactive Biphenyls to Cyclohexadienones

Organic Letters, 2022
An efficient electrooxidative dearomatization of inactive biphenyls has been developed under mild and easy-to-operate conditions. The protocol provides a powerful tool for the rapid synthesis of cyclohexadienones in moderate to high yields with wide substrate scope and good functional group compatibility even to oxidation-sensitive motifs.

Silver nanoparticles electrooxidation: theory and experiment

Journal of Solid State Electrochemistry, 2011
This article presents the findings of microscopic and electrochemical studies of electrooxidation of silver nanoparticles of varying sizes in comparison with "bulk" silver. Silver particles were immobilized on the surface of indifferent carbon-containing screen-printed electrodes. Vacuum-deposited silver represented the "bulk" electrode.

Shrinking Nanowires by Kinetically Controlled Electrooxidation

The Journal of Physical Chemistry B, 2005
Nanowires composed of antimony, gold, and bismuth telluride (Bi2Te3) were reduced in diameter by electrooxidation in aqueous solutions. When electrooxidation was carried out using low current densities (Jox < 150 microA cm(-2)), the mean wire diameter decreased in direct proportion to the oxidation time, as expected for a kinetically controlled process.

Pyrrhotite Electrooxidation in Acid Solutions

Russian Journal of Electrochemistry, 2001
The electrooxidation of pyrrhotite, including that preliminarily etched in acid solutions, is studied by voltammetry, scanning electron microscopy, and X-ray electron spectroscopy. The oxidation mechanism includes the formation; “reversible” oxidation (which predominantly involves an increase in the amount of polysulfide ions) of a near-surface ...

Electrooxidation of Propylene to Acrolein

ECS Meeting Abstracts, 2018
Short chain alkanes and alkenes (C1-4) typically have little economic value and are difficult to transport since they are gases. Because of this, these hydrocarbons are of so low value that they are often flared during extraction of oil.1 This talk investigates electrochemically partially oxidizing these materials to high-value liquid products, thus ...
