DMDO epoxidation of bromoallenes gives directly α,β-unsaturated carboxylic acids under the reaction conditions. Calculated (ÏB97XD/6-311G(d,p)/SCRF = acetone) potential energy surfaces and 2H- and 13C-labeling experiments are consistent with bromoallene oxide intermediates which spontaneously rearrange via a bromocyclopropanone in an intersecting bromoallene oxide â Favorskii manifold.
