the rearrangement of a carbocation to a more stable carbocation steps: 1. identify all adjacent carbons to positive charge, 2. identify all -H and -CH3 groups that are capable of shifting 3. imagine each of the groups shifting to see which yields the most stable resulting carbocation

This fresh carbocation is right next to our aromatic ring and is stabilized by resonance, making it a significantly more favorable candidate for reactions. In the realm of organic chemistry, this migration is termed the “1,2-hydride shift.”. It’s as if we’re gently nudging the hydrogen to a new position.
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.
Jan 23, 2023 · 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. Often a substituent moves from one atom to another atom in the same molecule.

A 1,2-rearrangement is an organic reaction where a substituent moves from one atom to another atom in a chemical compound. In a 1,2 shift the movement involves two adjacent atoms but moves over larger distances are possible. Skeletal isomerization is not normally encountered in the laboratory, but is the basis of large applications in oil ...
