摘要:
The reaction of [OS3(CO)11(NCMe)] with bis(trifluoromethyl)telluride, Te(CF3)2, in cyclohexane yields the cluster [OS3(CO)11{Te(C6H11)2}] 2 in which the CF3 substituents at the tellurium are replaced by two cyclohexyl substituents; the isolation of the intermediate [OS3(CO)11{Te(CF3)(C6H11)} 1 in the dark reveals that the first C-H activation of the cyclohexane is a thermal process, whereas the second C-H activation requires sunlight.
