Die Pummerer-Umlagerung ist eine organisch-chemische Reaktion, in der Sulfoxide mit Anhydriden umgesetzt werden kΓΆnnen. Die ΓΌber verschiedene Zwischenstufen entstehenden Produkte sind Ξ±-Acyloxysulfide, die als synthetisches Γquivalent zu geschΓΌtzten Carbonylverbindungen dienen kΓΆnnen. Die Reaktion wurde nach ihrem Entdecker Rudolf Pummerer (1882β1973) benannt.cite-ref-1[1]cite-ref-2[2]
Die Pummerer-Umlagerung findet sich auch als Nebenreaktion der Swern-Oxidation.
