title: Photoinduced electron-transfer bicyclopropenyl-benzene rearrangements of 2,2',3,3'-tetraphenylbicyclopropenyls: a new mechanism via Dewar benzene.
abstract: [reaction: see text] The 9,10-dicyanoanthracene-sensitized photoreaction of 1-methyl- and 1,1'-dimethyl-2,2',3,3'-tetraphenylbicyclopropenyl gives the corresponding benzene and Dewar benzene derivatives, indicating that their photoinduced electron-transfer bicyclopropenyl-benzene rearrangements proceed via Dewar benzenes.
