Radicalcation vinylcyclopropane rearrangements by TiO2 photocatalysis in lithium perchlorate/nitromethane solution are described. The reactions are triggered by oxidative single electron transfer, which is followed by immediate ring-opening of the cyclopropanes to generate distonic radicalcations as unique reactive intermediates. This approach can also be applied to vinylcyclobutane, leading to the
