The mechanistic aspects of the redox-photosensitized chain cycloreversion of trans,syn-indene dimer 1 have been investigated in detail.The ? complex of 1 with the cation radical of phenanthrene (and selected other aromatic hydrocarbons) that is generated by photochemical electron transfer with p-dicyanobenzene has been shown to be a key intermediate by way of which the cycloreversion of 1 rapidly occurs without the formation of its cation radical; the rate constant for the cycloreversion has been determined to be 1*109 s-1.Redox photosensitization has been applied to the other related compounds and it has been found that the cyclobutanes which can undergo redox-photosensitized ring cleavage possess the phenyl group at C2.The importance of through-bond interactions between the two ?-electron system is discussed.
