“Fluor” it: Palladium‐catalyzed tandem reactions, in which C(sp3)H bond activation is the key step (see scheme; DMA=dimethylacetamide), lead to substituted fluorenes and indenofluorenes through annulation in high yield and in one step. This method has potential for the preparation of other cyclic compounds, as well as substituted oligofluorenes and polyfluorenes.
“ Fluor”:钯催化的串联反应,其中C(sp 3)H键的活化是关键步骤(请参阅方案; DMA =二甲基乙酰胺),通过高产率环合反应可生成取代的芴和茚并芴。该方法具有制备其他环状化合物以及取代的低聚芴和聚芴的潜力。
