Definition : In Dakin oxidation, aromatic aldehydes or ketones undergo treatment with RCO3H or H2O2 to smoothly oxidize them into carboxylic acids. The reaction operates effectively when the aromatic aldehyde or ketone possesses electron-rich (-R, -OH, -OR, -NH2, or -NHR) substituents in the para or ortho positions. When the aromatic ring is substituted with electron-withdrawing … Read more
Aza-Cope Rearrangement Mechanism, Examples and Applications
Baker-Venkataraman Rearrangement is the base-promoted (KOH) rearrangement of aromatic 2-acyloxy ketones to the corresponding aromatic 1,3-diketone (β-diketones)
Formation of α-substituted sulfides from the corresponding sulfoxides (must have at least one hydrogen atom at their α-position) is referred to as the Pummerer rearrangement.
The Aza-Claisen rearrangement is a chemical reaction involving a nitrogen atom’s migration from one position to another within a molecule. It is named after the Claisen rearrangement, a well-known rearrangement reaction involving oxygen atoms. The mechanism of the aza-Claisen rearrangement: The mechanism of the aza-Claisen rearrangement involves three steps: Protonation: The reaction often starts with … Read more
Schmidt reaction is a acid-catalyzed Rearrangement reaction of hydrazoic acid reactions of electrophiles, like carbonyl compounds, alkenes tertiary and alcohols. The following these substrates include amines, nitriles, amides or imines, rearrangement and extrusion of nitrogen.
