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...
Pinacol is a white solid organic compound. It is a diol that has hydroxyl groups (-OH) on vicinal carbon atoms. It may be produced by the pinacol coupling...
A pinacol coupling reaction is an organic reaction in which a carbon–carbon bond is formed between the carbonyl groups of an aldehyde or a ketone in presence...
conjugate addition also in conjunction with a metal. In one study the pinacol ester of allylboronic acid is reacted with dibenzylidene acetone in such...
reaction at room temperature. The Prins-pinacol reaction is a cascade reaction of a Prins reaction and a pinacol rearrangement. The carbonyl group in the...
rearrangements. While similar to the pinacol rearrangement, the semipinacol rearrangement differs from the pinacol rearrangement in that the cation is...
Wilhelm Rudolph Fittig (1835–1910), German chemist. He discovered the pinacol coupling reaction. Wilhelm Kühne (1837–1900), German physiologist. He coined...

carbon is a pinacol rearrangement. While this reaction refers specifically to a vicinal dihydroxide rearrangement, there are other pinacol type rearrangements...
Baeyer-Villiger reaction, the more substituted group, in general, migrates. In the pinacol rearrangement, the order of migratory aptitude has not been determined...
in the classroom, pinacolone arises by the pinacol rearrangement, which occurs by protonation of pinacol (2,3-dimethylbutane-2,3-diol). Industrially...

Dimethylbutadiene is readily prepared by an acid catalyzed dehydration reaction of pinacol: HO(CH3)2C−C(CH3)2OH → CH3(CH2=C−C=CH2)CH3 + 2 H2O The current industrial...
December 1835 – 19 November 1910) was a German chemist. He discovered the pinacol coupling reaction, mesitylene, diacetyl and biphenyl. Fittig studied the...
acid. Other routes to vic-diols are the hydrogenation of acyloins and the pinacol coupling reaction. 1,3-Diols are often prepared industrially by aldol condensation...
