Abstract

The reaction of [(η⁵-C₅Me₅)₂Sm(THF)₂] with SO₂ resulted in four different products. The dimeric samarium complex [{(η⁵-C₅Me₅)₂Sm(C₅Me₅SO₂)}₂] (1) crystallized from the reaction mixture first. The dithionite-sulfinate complex [{(η⁵-C₅Me₅)₂Sm(S₂O₄)}₂{(η⁵-C₅Me₅)Sm(C₅Me₅SO₂)}₂] (2), was obtained as the second major product after workup of the filtrate. Additionally, the dithionite complex [{(η⁵-C₅Me₅)₂Sm}₂(S₂O₄)] (3) and the sulfinate complex [{(η⁵-C₅Me₅)Sm}₂(C₅Me₅SO₂)₄] (4) were isolated as minor products. All compounds were characterized by single crystal X-ray diffraction. As major reaction pathways, the reductive coupling of two SO₂ molecules to form the dithionite anion S₂O₄^2- and the nucleophilic attack of one samarocene C₅Me₅ ligand on the sulfur atom of SO₂ were observed.
