title: Photolysis of diarylvinylcyclopropenes for the construction of 1-methylene-8a-aryl-1,8a-dihydroazulene skeletons.
abstract: Photoirradiation of vinylcyclopropenes in a Pyrex tube provides 1-isopropylidene-3,8a-diphenyl-1,8a-dihydroazulene derivatives in moderate to good yields within 4.5-14 h. A plausible mechanism has been discussed for the formation of these interesting products.
