摘要

苯酚选择性氢脱氧制芳烃对木质素衍生的含氧化合物转化为高附加值芳香化学品具有重要意义。在这里，我们报道了偏磷酸铝负载的Pt纳米颗粒（Pt/Al(PO3)3）在温和条件下（低至150°C），以环烷烃为氢源，选择性地将苯酚转移氢解为芳烃。除取代苯酚外，本催化剂体系还可用于取代儿茶酚或愈创木酚。

Pt/Al(PO3)3-Catalyzed Transfer Hydrogenolysis of Phenols to Arenes Using Cyclic Alkanes as the Hydrogen Source

The selective hydro-deoxygenation of phenols to arenes is of importance for upgrading lignin-derived oxygenates to value-added aromatic chemicals. Here, we report aluminum metaphosphate-supported Pt nanoparticles (Pt/Al(PO₃)₃) for selective transfer hydrogenolysis of phenols to arenes using cyclic alkanes as the hydrogen source under mild conditions (as low as 150 °C). In addition to substituted phenols, the present catalyst system can also be applied to a substituted catechol or guaiacol.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
