The phototransformation of the following 2-amino-Δ2-thiazoline derivatives have been studied: 4-chlorobenzoyl, 4-methyl benzoyl, benzoyl, 2-chloro benzoyl, 2-methyl benzoyl.Irradiation of a deaerated cyclohexane solution of these compounds gave corresponding derivatives of N-ethyl N'-benzoyl thiurea, the formation of which may be rationalized by homolytic cleavage of the C-S bond followed by hydrogen abstraction from the solvent.According to photophysical data previously obtained, a kinetic model is proposed.The relative values of the formation rate constant of a biradical intermediate are calculated and a relation between this rate constant and the first triplet state energy is established.UV, IR, 1H NMR and 13C NMR spectra of the photoproducts have been recorded and the main spectral data are presented.
