methylnaphthalenes, which could capture alkyl radicals via SOMO–LUMO interactions, enabled the development of Cu-catalyzed formal [4 + 2] and [3 + 2] cycloadditions between methylnaphthalenes and electron-deficient alkenes. Under copper catalysis, a series of electron-deficient alkenes and methylnaphthalenes with different substituents were successfully incorporated with di-tert-butyl peroxide (TBP) as

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
