Photolytic homolysis of the alkyl cobalt ‘salophens’ (10), (20a) and (20b) in the presence of radical trapping agents e.g. O2, TEMPO, NO, SO2, PhSSPh, PhSeSePh, MeSO2Cl, BrCCl3 and I2, leading to oxygen, nitrogen, sulphur, selenium and halogen functionalised products, is used to demonstrate the versatility of cobalt-mediatedradical reactions in synthesis.
