Photoreaction of a 2,11-Diaza[3.3]paracyclophane Derivative: Formation of Octahedrane by Photochemical Dimerization of Benzene

摘要

Photoreactions of the benzenes which are incorporated in a cyclophane have been of interest because their reaction modes reflect the intramolecular interactions of the aromatic chromophores in the cyclophane system.Prinzbach et al.reported the [6 + 6] photocycloaddition of benzenes,and Misumi et al.investigated the photolysis of four-layered cyclophanes to demonstrate the formation of cage-like benzene dimers.Recently,Shinmyozu et al.reported that,upon the photolysis of carbon-bridged cyclophanes,polycyclic products were formed through complex rearrangements.
