Photoreactions of 4-methylenebicyclo[3,2,0]hept-2-enes
Abstract
4-Methylenebicyclo[3,2,0]hept-2-enes are shown to undergo photofragmentation reactions from the excited singlet state and, depending on the substitution pattern, may undergo rearrangement to norbornene derivatives from both singlet and triplet states.
