Catalyzed by acid, the reactions of arylvinylcycloproenes with acetals or aldehydes lead to different cascade additions to construct different aromatic systems (see scheme).

Photoirradiation of vinylcyclopropenes 1 in a Pyrex tube provides 1-isopropylidene-3,8a-diphenyl-1,8a-dihydroazulene derivatives 2 in moderate to good yields within 4.5–14 h. A plausible mechanism has been discussed for the formation of these interesting products.
