The Elbs persulfate oxidation is the organic reaction of phenols with alkaline potassium persulfate to form para-diphenols. [1] The reaction is generally performed in water at room temperatures or below, using equimolar quantities of reagents. The Elbs persulfate oxidation. Several reviews have been published. [2] [3] [4]
Electron transfer reactions are central to myriad processes and properties in soils, and redox potential, quantified as Eh (platinum electrode potential relative to the standard hydrogen electrode) or pe (analogous to pH as -log electron activity), is a master variable, along with pH, that controls and is governed by chemical reactions and ...
The following scheme shows the reaction mechanism: Stephen aldehyde synthesis: Reaction mechanism. By addition of hydrogen chloride the used nitrile (1) reacts to its corresponding salt (2). It is believed that this salt is reduced by a single electron transfer by the tin(II) chloride (3a and 3b). [3]
First performed by Justus von Liebig in 1838, [1] it is the first reported example of a rearrangement reaction. [2] It has become a classic reaction in organic synthesis and has been reviewed many times before. [3] [4] [5] It can be viewed as an intramolecular redox reaction, as one carbon center is oxidized while the other is reduced. Scheme 1.
Example of a reduction–oxidation reaction between sodium and chlorine, with the OIL RIG mnemonic [1] Electron transfer (ET) occurs when an electron relocates from an atom, ion, or molecule, to another such chemical entity. ET describes the mechanism by which electrons are transferred in redox reactions. [2] Electrochemical processes are ET
The Wolff–Kishner reduction is a reaction used in organic chemistry to convert carbonyl functionalities into methylene groups. [1] [2] In the context of complex molecule synthesis, it is most frequently employed to remove a carbonyl group after it has served its synthetic purpose of activating an intermediate in a preceding step.
Many redox reactions in organic chemistry have coupling reaction reaction mechanism involving free radical intermediates. True organic redox chemistry can be found in electrochemical organic synthesis or electrosynthesis. Examples of organic reactions that can take place in an electrochemical cell are the Kolbe electrolysis. [3]
The Bouveault–Blanc reduction is a chemical reaction in which an ester is reduced to primary alcohols using absolute ethanol and sodium metal. [1] It was first reported by Louis Bouveault and Gustave Louis Blanc in 1903.
