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.
在自由基捕获剂(例如O 2,TEMPO,NO,SO 2,PhSSPh,PhSeSePh,MeSO 2 Cl,BrCCl 3和I )存在下,对烷基钴“ salophens”(10),(20a)和(20b)进行光解均质如图2所示,其导致氧,氮,硫,硒和卤素官能化的产物被用来证明钴介导的自由基反应在合成中的多功能性。
