A novel Rh(III)-catalyzed relay cross-coupling/cyclization cascade between arylketoimines and diazoesters is described. This transformation provides a concise access to unique π-conjugated 1-azaphenalenes (1-APLEs) via a double aryl Csp(2)-H bond carbenoid functionalization process. As illustrative examples, the 1-APLE-based π-conjugated molecules which possess low-lying HOMO levels could be converted to promising organic optoelectronic materials.
描述了一种新型铑（III）催化的芳基酮亚胺与重氮酯之间的接力交叉偶联/环化串联反应。这种转化通过双芳基Csp(2)-H键类卡宾官能化过程，为独特的π共轭1-氮杂菲（1-APLEs）提供了一种简洁的合成方法。作为示例，具有低HOMO能级的基于1-APLE的π共轭分子可转化为有前景的有机光电子材料。
