a carbocation, or a free radical; or if the substrate is aliphatic or aromatic. Addition Reaction The addition reaction in organic chemistry may simply be defined as a chemical change where two or more molecular entities combine to give rise to a bigger molecule (i.e., the adduct). Also, since the incoming
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 ...
NH. H. (100%) N. ". . . after ca. 10 seconds, a relatively violent reaction occurred which was accompanied by a dense cloud of white smoke and change in color from the characteristic yellow-green of the starting material to a dark brown."

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.
Oct 17, 2011 · Introduction to Rearrangement Reactions. Reactions that involve a carbocation intermediate may be accompanied by rearrangements where a pair of electrons from a C-H or C-C bond migrates toward the carbocation, resulting in breakage and formation of a C-H or C-C bond, and formation of a new carbocation. The new carbocation (generally more stable ...

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.
