Siloxides as Supporting Ligands in Uranium(III)‐Mediated Small‐Molecule Activation

Siloxides can support U! …︁in the reduction of small molecules with uranium complexes. The treatment of [U{N(SiMe3)2}3] with HOSi(OtBu)3 (3 equiv) yielded a novel homoleptic uranium(III) siloxide complex 1, which acted as a two-electron reducing agent toward CS2 and CO2 (see scheme). Complex 1 also reduced toluene to afford a diuranium inverted-sandwich complex.
