Starting from bicyclo[3.3.0]octa-3,7-diones, several 3- and 7-substituted semibullvalenes were prepared. Cycloaddition of N-phenyltriazolindione to some of these semibullvalenes lead with rearrangement of the carbon skeleton to dihydrodiazatriquinacenes. Deazoniation of the diazatriquinacenes obtained from the cycloadducts above occurred at 80° to semibullvalenes.
