Most famously, at least in the classroom, pinacolone arises by the pinacol rearrangement, which occurs by protonation of pinacol (2,3-dimethylbutane-2,3-diol). [4] Industrially pinacolone is made by the hydrolysis of 4,4,5-trimethyl-1,3-dioxane, which is the product of isoprene and formaldehyde via the Prins reaction.
Neopentyl glycol (IUPAC name: 2,2-dimethylpropane-1,3-diol) is an organic chemical compound. It is used in the synthesis of polyesters , paints , lubricants , and plasticizers . When used in the manufacture of polyesters, it enhances the stability of the product towards heat, light, and water.
Pinacol is a branched alcohol which finds use in organic syntheses. It is a diol that has hydroxyl groups on vicinal carbon atoms. A white solid that melts just above room temperature, pinacol is notable for undergoing the pinacol rearrangement in the presence of acid and for being the namesake of the pinacol coupling reaction.
2,3-Dimethylbutane is an isomer of hexane. It has the chemical formula (CH 3) 2 CHCH(CH 3) 2. It is a colorless liquid which boils at 57.9 °C. References
Pinacolyl alcohol (also known as 3,3-dimethylbutan-2-ol and as pine alcohol) is one of the isomeric hexanols and a secondary alcohol. Pinacolyl alcohol appears on the List of Schedule 2 substances of the Chemical Weapons Convention as a precursor for the nerve agent soman .

The pinacol–pinacolone rearrangement is a method for converting a 1,2-diol to a carbonyl compound in organic chemistry. The 1,2-rearrangement takes place under acidic conditions. The name of the rearrangement reaction comes from the rearrangement of pinacol to pinacolone. [1]
Dimethylbutadiene, formally referred to as 2,3-dimethyl-1,3-butadiene, is an organic compound with the formula (CH 3) 2 C 4 H 4. It is colorless liquid which served an important role in the early history of synthetic rubber .
