Reference Information


Dimethyldioxirane (DMDO) is a dioxirane derived from acetone. It is the most commonly used dioxirane in organic synthesis, and can be considered[citation needed] as a monomer of acetone peroxide.

DMDO is not commercially available because of its instability. DMDO can be prepared by the reaction of acetone with oxone, where the potassium peroxymonosulfate is the active ingredient:[1]

The preparation of DMDO is rather inefficient (typical yields < 3%) and typically only yields a relatively dilute solution in acetone (only up to approximately 0.1 M). However, this is of no consequence, since DMDO is prepared from extremely cheap starting materials: acetone, sodium bicarbonate, and potassium peroxymonosulfate (commercially known as "oxone"). The solution can be stored at low temperatures and assayed immediately prior to use to determine its actual concentration.
