Methylenecyclobutanes undergo Wacker oxidation towards cyclopentanones under mild reaction conditions. A semi-pinacol-type rearrangement is proposed to be responsible for the intermediary 1,2-shift, which not only explains the formation of the products, but also rationalizes the reaction outcomes in terms of site-, regio- and enantioselectivity.
