method has been an elusive goal. A trifluoromethyl ketone catalyst in combination with Oxone is shown to enable the first dioxirane-mediated catalytic hydroxylations that approximate the reactivity and selectivity of isolated dioxiranes. The mild reaction conditions allow for selective 3° hydroxylation and 2° oxidation and are tolerant of acid-sensitive functionality and electron-neutral arenes.
