CC Bond Formation through Reductive Coupling of CS₂ to Yield Uranium Tetrathiooxalate and Ethylenetetrathiolate Complexes

A novel twist: The UIII complex [((AdArO)3N)U] reacts with CS2 by reductive coupling to form the tetrathiooxalate complex [{((AdArO)3N)U}2(μ-κ2:κ2-C2S4)] with a newly formed CC bond (see scheme). The UIV/UIV tetrathiooxalate complex features a nonplanar C2S42− unit in an unprecedented μ-κ2:κ2 binding mode. Further reduction gives the ethylenetetrathiolate complex [Na(dme)3]2[{((AdArO)3N)U}2(μ-C2S4)]. DME=1,2-dimethoxyethane.
