What is Favorskii Rearrangement explain? Favorskii Rearrangement is organic reaction of α-halo ketones (chlorine, bromine, or iodine) having at least one α-hydrogen, with a nucleophile (alcohol, amine, or H2O) in the presence base (usually an alkoxide or hydroxide) give carboxylic acids or carboxylic acid derivatives via a cyclopropanone intermediate. It is widely used organic reaction … Read more
The conversion of ketone (cyclic ketone, aromatic ketone, aliphatic ketone) into corresponding esters (lactones) by using MCBPA, or hydrogen peroxide as oxidant and a Lewis acid is known as Baeyer-Villiger oxidation (Baeyer-Villeger Reaction).
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)
The formation of oxacyclic and carbocyclic ring systems by terminating Prins cyclizations with the pinacol rearrangement in a tandem fashion is known as the Prins-pinacol rearrangement.
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.
