Perhydrolysis in Ethereal H2O2 Mediated by MoO2(acac)2: Distinct Chemoselectivity between Ketones, Ketals, and Epoxides.

Ketones, ketals, and epoxides were converted into corresponding hydroperoxides in high yields by reaction with ethereal H2O2 in the presence of a catalytic amount of MoO2(acac)2 with distinct (to date unattainable) chemoselectivity.
