pinacol rearrangement

The pinacol coupling can be followed up by a pinacol rearrangement.

In some cases the reaction type is also called a retropinacol rearrangement (see Pinacol rearrangement).

Diols can undergo pinacol rearrangement under fluorination conditions.

In his second publication in 1860 he reacted paraceton with sulfuric acid (the actual pinacol rearrangement).

The Prins-pinacol reaction is a cascade reaction of a Prins reaction and a pinacol rearrangement.

The pinacol rearrangement or pinacol-pinacolone rearrangement is a method for converting a 1,2-diol to a carbonyl compound in organic chemistry.

Pinacolone may be prepared via the pinacol rearrangement of pinacol, e.g. by heating with sulfuric acid:

As a vicinal-diol, it can rearrange to pinacolone by the pinacol rearrangement, e.g. by heating with sulfuric acid:

Although Fittig first published about the pinacol rearrangement,it was not Fittig but Aleksandr Butlerov who correctly identified the reaction products involved.

While similar to the pinacol rearrangement, the semipinacol rearrangement differs from the pinacol rearrangement in that the cation is not formed from a vicinal 1,2-diol.
