to the construction of other polycyclic aromatic hydrocarbons (PAHs), such as chrysene, helicene, and pyrene having a phenanthrene backbone, via regioselective cyclization. This method has the advantages of easy availability of the cyclization precursors, operational simplicity, and high reaction efficiency.
2-(2-芳基苯基)乙烯基醚在催化量的三氟甲磺酸铋(III)存在下的反应在温和的反应条件下以极好的收率得到了取代的菲。该反应还通过区域选择性环化反应被用于构建其他多环芳烃(PAH),例如具有菲主链的菲,lic烯和pyr。该方法具有容易获得环化前体,操作简单和高反应效率的优点。
