Dimethyldioxirane
Dimethyl dioxirane (DMDO) is a highly reactive electrophilic oxidant belonging to the family of dioxiranes, a class of highly strained three‑membered rings containing two adjacent oxygen atoms and one carbon atom. In DMDO, the ring carbon bears two methyl substituents, giving a compact, potent oxygen-transfer reagent. It is typically generated in situ in acetone solution and used directly for oxidations.
Preparation and handling: DMDO is prepared by oxidizing acetone with an oxygen‑bearing oxidant, commonly potassium peroxymonosulfate
Reactivity and applications: DMDO transfers an oxygen atom to alkenes to form epoxides under mild conditions,
Safety and scope: As an energetic, highly oxidizing species, DMDO requires careful handling, cold storage, and
