Pinacolone (3,3-dimethyl-2-butanone) is an important ketone in organic chemistry. It has an odour reminiscent of peppermint and was discovered in 1866. Its primary use is in the synthesis of triazolylpinacolone in the synthesis of the fungicide triadimefon and in synthesis of the herbicide metribuzin.
Pinacolone may be prepared via the pinacol rearrangement of pinacol, e.g. by heating with sulfuric acid:[1]
