We report a straightforward, metal-free, efficient protocol for the synthesis of 2-phenylnaphthalenes from 1-phenylethane-1,2-diols under mild conditions. In this strategy, 1,1,1,3,3,3-hexafluoro-2-propanol is used as a solvent that stabilizes the reaction intermediate. An in situ IR experiment revealed that the reaction proceeds through the formation of phenylacetaldehyde followed by a [4+2] Diels–Alder
我们报告了一种在温和条件下从 1-苯基乙烷-1,2-二醇合成 2-苯基萘的简单、无金属、有效的方案。在该策略中,1,1,1,3,3,3-六氟-2-丙醇用作稳定反应中间体的溶剂。原位 IR 实验表明,该反应通过苯乙醛的形成以及 [4+2] Diels-Alder 反应进行。进行了几个对照实验以获得对反应的机理见解。
