Abstract

The radiation induced keto—enol and chelate—carbeniate tautomerization of some β-dicarbonyl compounds and their copper complexes is studied in solution and in polymer (PVC) film. The samples are subjected to irradiation using a 60Co source. The effects of the kGy doses in air on the percentage of the enol or chelate forms are investigated with UV- and IR-spectral methods. These radiation induced processes are discussed in terms of the mechanism proposed previously for the photoinduced ketonization and metallotropy of β-dicarbonyl compounds.
