The synthesis of 9‐fluorenone derivatives has been achieved in high yield and with high purity by aerobic oxidation of 9 H ‐fluorenes at room temperature in the presence of a graphene‐supported KOH composite that acts as a catalyst in N,N ‐dimethylformamide. The new protocol involves very simple work‐up procedures, and the solvent and the catalyst can be recycled and reused. A scaled‐up preparative study employing this method was also conducted and showed its advantages of being both cost‐effective and environmentally friendly, and has potential for application in industrial processes.
