N-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.
通过使二苯并亚甲基三酮与一系列取代的二氨基-和四氨基-芳烃缩合获得一系列的二苯并亚砜基-稠合的N-杂蒽。缺电子的三酮在室温下反应,并以良好至极佳的产率提供含吡嗪或双吡嗪的缩合产物。靶都根据单晶结构显示负曲率。
