The insertion of sulfur dioxide into the Co−C bond in ArCH2Co(dioxime)2Py forms a mixture of ArCH2SO2Co(dioxime)2Py, ClCo(dioxime)2Py, and a neutral trinuclear complex, [(dpgH)2PyCoIII-μ-SO3]2CoII(MeOH)4. The inserted products 4-CN-C6H4CH2SO2Co(dpgH)2Py and C6H5CH2SO2Co(gH)2Py and the trinuclear complex have been structurally characterized by X-ray for the first time. The insertion of sulfur dioxide into the Co−C bond affects the orientation of the benzyl group.
