Bis(1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane) peroxodisulfate: A mild and efficient oxidant for cleavage of nitrogen double bonds and oxidation ofalcohols under anhydrous conditions

Bis(1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane) peroxodisulfate (1), is re adily prepared as an orange solid from commercially available 1,4-diazabicy clo[2.2.2]octane and potassium peroxodisulfate. This reagent easily convert s hydrazones, semicarbazones, oximes, and alcohols to the corresponding car bonyl compounds with excellent yields.
