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.
从双环[3.3.0]八-3,7-二酮开始,制备了几种3-和7-取代的半牛戊烯。N-苯基三唑啉二酮与这些半布尔戊烯中的一些环加成导致碳骨架重排成二氢二氮杂三喹并酮。由以上环加合物获得的二氮杂三喹并酮在80°发生脱氮重氮反应。
