本文描述了钯催化的芳香族碘化物、双环烯烃（降冰片二烯、异冰片烯和氧杂苯并降冰片二烯）和苯炔的碳环化反应，得到各种环状的9，10-二氢菲衍生物。氧杂苯并降冰片二烯的碳环化产物通过刘易斯酸介导的脱氧芳构化反应进一步转化为多环芳烃。
A facile palladium-catalyzed carbocyclization reaction of aromatic iodides, bicyclic alkenes (norbornadiene, norbornene and oxabenzonorbornadiene), and benzynes to furnish various annulated 9,10-dihydrophenanthrene derivatives is described. The carbocyclization products from oxabenzonorbornadiene were further converted to polyaromatic hydrocarbons via a Lewis acid mediated deoxyaromatization reaction.
