摘要

An efficient, catalytic hypervalent iodine-mediated oxidative 1, 2-shift of 1, 1′-disubstituted olefins is described. This methodology provides concise access to homobenzylic ketones with electron-donating substituents. In the case of cyclic systems, this transformation results in ring-expanded β-benzocycloalkanones, which are useful for further elaboration.
