我们报告的热C-F键活化的氟代芳烃的各种金属氧化物，导致有效的C-C键的形成，通过环脱氢。我们证明，前体分子的转换到相应的模型nanoglene/nanoriginates可以实现相当有效地在各种金属氧化物。发现分子内芳基-芳基环化反应可以在相对温和的条件下进行。我们的发现为直接在绝缘金属氧化物表面上通过自下而上的策略合理合成碳基纳米材料开辟了一个途径。
We report on thermal C-F bond activation in fluoroarenes by various metal oxides leading to effective C-C bond formation via cyclodehydrofluorination. We demonstrate that the transformation of the precursor molecule to the respective model nanographene/nanoribbon can be realized rather effectively on various metal oxides. It is found that intramolecular Aryl-Aryl cyclization via cyclodehydrofluorination can be performed at relatively mild condition. Our finding opens up a venue toward rational synthesis of carbon-based nanomaterial by bottom-up strategy directly on insulating metal oxide surfaces.
