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 ...

Rearrangement Reactions A rearrangement reaction is a broad class of organic reactions where the carbon skeleton of a molecule is rearranged to give a structural isomer of the original molecule. 1, 2-Rearrangements A 1, 2-rearrangement is an organic reaction where a substituent moves from one atom to another atom in a chemical compound.

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.

Rearrangement reactions can accompany many of the reactions we’ve previously covered such as substitution, addition, and elimination reactions. 1. Substitution (SN1) (See post: Alkyl Halides From Alcohols) 2. Elimination (E1) (See post: Elimination (E1) With Rearrangement) 3. Alkene addition reactions (See post: Rearrangements in Alkene Addition Re...
In fact, if you don’t look closely, sometimes you can miss the fact that a rearrangement reaction has occurred. Let’s look at a substitution reaction first. On the top is a “typical” substitution reaction: we’re taking an alkyl halide and adding water. The C-Br bond is broken and a C-OH bond is formed. If you look at the table on the right you’ll s...
Let’s look at another example, but involving an addition reaction (the addition of HCl to alkenes). Here we have an addition reaction. On top, nothing special – as with all additions, we break a C-C double bond (π bond )and form two new single bonds to the adjoining carbons (H and Cl). But look at the bottom example. If we use that alkene instead, ...
Finally, let’s look at an elimination reaction. If you take an alcohol like the one below and add an acid (like H2SO4, pictured) and help the reaction along with some heat, you break the C1-OH and C2-H bonds, and form a new double bond between C1-C2. This is, in other words, a typical elimination reaction. But if you take a slightly modified alcoho...
