本文报道了在碳酸存在下三芳基膦与烯烃的光诱导反应。发生剧烈的结构变化，产生具有磷酸三环[4.3.0.02.9]壬烯核结构的熔融三环磷酸盐。该反应的标志是苯环的脱芳化转环，磷原子的1,2-迁移和烯烃的掺入。在温和的反应条件下，可见光与光催化剂的协同作用促进了高吸氧过程。
Herein reported is a photoinduced reaction of triarylphosphines with alkenes in the presence of carbonic acid. A drastic structural change occurs to produce fused tricyclic phosphonium salts having a phosphatricyclo[4.3.0.02.9]nonene core structure. The reaction was marked by dearomatizing transannulation of the phenyl ring, 1,2-migration of the phosphorus atom, and incorporation of an alkene. The highly endergonic process is promoted by cooperation of visible light with a photocatalyst under mild reaction conditions.
