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).
The willgerodt kindler reaction is the modification of the Willgerodt Reaction. It comes under a Rearrangement reaction. The name has been given after Karl Kindler.
Arndt-Eistert Reaction
The Appel reaction is a common organic nucleophilic substitution reaction (SN2) employed to transform alcohol to a corresponding alkyl halide using the reagents tetrahalomethane (CX4) and triphenylphosphine (PPh4) with inversion of stereochemistry and high yield.
The acid catalysed three-component one-pot synthesis of highly functionalized 3,4-dihydropyrimidin-2(1H)-ones (DHPMs) from biginelli reaction reactants heteroaromatic, aromatic and aliphatic aldehyde, urea, and ethyl acetoacetate.
