Jp. Dinnocenzo et Da. Conlon, THE CATION-RADICAL VINYLCYCLOPROPANE-]CYCLOPENTENE REARRANGEMENT - REACTION-MECHANISM AND PERISELECTIVITY, Tetrahedron letters, 36(41), 1995, pp. 7415-7418
The vinylcyclopropane-->cyclopentene rearrangement catalyzed by one-el
ectron oxidation has been shown to be most consistent with a stepwise,
cation radical mechanism. It was also discovered that the formal rear
rangement periselectivity of vinylcyclopropanes with cis-alkyl substit
uents can be changed by one-electron oxidation.
