Abstract

The reaction of decamethylytterbocene [(η⁵-C5Me5)2Yb(THF)2] with SO2 at low temperature gave two new compounds, namely, the Yb^III dithionite/sulfinate complex [{(η⁵-C5Me5)2Yb(μ3,1κ²O^1,3,2κ³O^2,2′,4-S2O4)}2{(η⁵-C5Me5)Yb(μ,1κO,2κO′-C5Me5SO2)}2] (1) and the Yb^III dithionite complex [{(η⁵-C5Me5)2Yb}2(μ,1κ²O^1,3,2κ²O^2,4-S2O4)] (2). After extraction of 1, the mixture was heated to give the dinuclear tetrasulfinate complex [{(η⁵-C5Me5)Yb}2(μ,κO,κO'-C5Me5SO2)4] (3 a). In contrast, from the reaction of [(η⁵-C5Me5)2Eu(THF)2] with SO2 only the tetrasulfinate complex [{(η⁵-C5Me5)Eu}2(μ,κO,κO'-C5Me5SO2)4] (3 b) was isolated. Two major reaction pathways were observed: 1) reductive coupling of two SO2 molecules to form the dithionite anion S2O4^2-; and 2) nucleophilic attack of one metallocene C5Me5 ligand on the sulfur atom of SO2. The compounds presented are the first dithionite and sulfinate complexes of the f-elements.
