TRIPLET BENZENE-SENZITIZED CYCLOREVERSION OF ARYLCYCLOBUTANE

Article abstract of DOI:10.1246/cl.1980.145

γ-Radiolysis of triphenylcyanocyclobutane (1) in benzene forms stilbene, cinnamonitrile and a stereo isomer of 1.The effect of additives and the kinetic treatment show that the cycloreversion of 1 proceeds by benzene triplet sensitization.Spectroscopic measurement in pulse radiolysis suggests the existence of 1,4-biradical as an intermediate.
