A series of dibenzosuberone-fused -heteroacenes was obtained by the condensation of dibenzosuberonetriketone with a series of substituted diamino- and tetramino-arenes. The electron-deficient triketone reacts at room temperature and furnishes the pyrazine or bis-pyrazine-containing condensation products in good to excellent yield. The targets all display negative curvature according to single crystal structures.
通过二苯并环庚三酮与一系列取代的二氨基和四氨基芳烃缩合，得到了一系列二苯并环庚三酮稠合的杂并四苯。缺电子的三酮在室温下反应，以良好至优异的产率提供含吡嗪或双吡嗪的缩合产物。根据单晶结构，目标产物均呈现负曲率。
