摘要

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.
