The Sommelet-Hauser rearrangement may simply be defined as the rearrangement reaction of certain benzyl quaternary ammonium salts where the reagent used is sodium amide (or alkali amide) and the reaction results in the N,N-dialkylbenzylamine with a new alkyl substituent in the aromatic o-position. Now because the final product is a benzylic ...
Benzilic Acid Rearrangement. The benzilic acid rearrangement involves conversion of a 1,2-diketone into a carboxylic acid. The conditions are deceptively simple, hydroxide followed by an acid quench, and lead to the migration of a benzene ring. This mechanism is relatively straightforward.
Rearrangement Reactions A rearrangement reaction in organic chemistry may simply be defined as a chemical change where the carbon skeleton of an organic compound rearranges itself to give rise to a structural isomer. Generally, a group moves from one atom to another atom within the same molecule.
1 RearrangementReactions. 1. Rearrangement ReactionsA rearrangement reaction is a board class of organic reactions in which an atom, ion, group of atoms, or chemical unit migrates from one atom to another atom in the same or different species, resulting in a structural isomer o.

Rearrangement reactions mostly involve breaking and/or making C—C, C—O, or C—N bonds. The migration origin is the atom from which the group moves, and the migration terminus is the atom to which it migrates. This chapter discusses the mechanism, experimental procedure, and applications of various rearrangement reactions, namely Baeyer ...

Bonding MO Antibonding MO. σ = C1ψ1 + C2 ψ2 σ* = (C1*)ψ1 + (C 2*) ψ. 2. The coefficients C1 and C2 represent the contribution of each AO. The squares of the C-values are a measure of the electron density on the atoms in question. Rule 3: Both wave functions must contribute one net orbital. Consider the C-O pi-bond.
