The Beckmann Rearrangement. Versatile reaction to make lactams and amides. Prepared starting from hydroxime, with many leaving groups possible. Alkyl group that migrates does so with retention of configuration, and is always anti to the oxime leaving group. E. Beckmann, Ber.

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 ...
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.
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
Our goal in this chapter is to introduce the most important rearrangements you will likely encounter in organic synthesis papers. We also know this will provide you with the skills to understand other reactions that you might encounter during your studies.
