xime with carbon tetrachloride and fluorotrichloromethane. However, no cyclisation was observed in the reactions of the ester, hex-2-one-3-oxo-5-enylcobaloxime, with carbon tetrachloride. These reactions are believed to take place by attack of a polyhalogenomethyl radical at the terminal unsaturated carbon of the organic ligand, followed either by an intramolecular homolytic displacement in which the
5-甲基六-5-苯基钴肟与四氯化碳和氟代三氯甲烷在80–100°C下反应,得到基本上纯的1-甲基-1-(β,β,β-三氯乙基)-和1-甲基-1-β-氟-β,β-二氯乙基)-环戊烷。己基-5-己烯基肟也可以从四氯化碳中生成三氯乙基环戊烷,但收率取决于四氯化碳的浓度。在六-3-氧代-5-烯基钴肟与四氯化碳和氟代三氯甲烷的反应中观察到类似的环化反应,得到三氯乙基或氟代二氯乙基四氢呋喃。然而,在酯,己二酮-3-氧代-5-烯基钴肟与四氯化碳的反应中未观察到环化。据信这些反应是通过在有机配体的末端不饱和碳上的多卤代甲基自由基的攻击而发生的,
