Photoreactions of 5-phenyl derivatives produce a product having tricyclo[6.3.0.01,4]undecadiene skeleton. Formation of angular triquinanes takes place in photoreactions of cycloalkene-linked cyanonaphthalenes. The observation demonstrates that π–π arene ring interactions, steric hindrance, and suitable locations of reaction sites in syn and anti singlet exciplexes govern the modes followed in intramolecular photoreactions
4-戊烯基-1-氰基萘的光反应产生螺环产物以及[4 + 2]环加合物。5-苯基衍生物的光反应产生具有三环[6.3.0.0 1,4 ]十一碳二烯骨架的产物。角三喹烷的形成发生在环烯烃连接的氰基萘的光反应中。观察表明,π-π芳烃环相互作用,空间位阻以及顺式和反单线态激基复合物中反应位点的适当位置控制着4-烯基-1-氰基萘分子内光反应中遵循的模式。
