| Abstract: | The activation of CS2 is of interest in a broad range of fields and, more particularly, in the context of creating new C?C bonds. The reaction of the dinuclear ytterbium(II) complex Yb2L4], 1 , L=(OtBu)3SiO?] with carbon disulfide led to the isolation of unprecedented reduction products. In particular, the crystallographic characterization of complex Yb2L4(μ-C2S2)], 2 , provided the first example of an acetylenedithiolate ligand formed from metal reduction of CS2. Computational studies indicated that this unprecedented reactivity can be ascribed to the unusual binding mode of CS22? in the isolated “key intermediate” Yb2L4(μ-CS2)], 3 , which results from the dinuclear nature of 1 . |
