  3. Die Pinakol-Umlagerung ist eine chemische Reaktion, bei der sich Di-tert-Glycole unter Einwirkung einer Protonensäure zu α-tertiären Ketonen umlagern. Der Name der 1860 erstmals beschriebenen Reaktion stammt von dem Trivialnamen des einfachsten derartigen Glycols, dem Pinakol. Die Reaktion wurde 1874 von dem russischen Chemiker Alexander Michailowitsch Butlerow als Umlagerung des Kohlenstoffgerüsts aufgeklärt. Die Reaktion besteht aus vier Teilschritten: Protonierung einer.
