Reduction of Rare-Earth Stannole Sandwich Complexes to Tin-Based Radical Ligands and Tin-Tin Bonds.

ABSTRACT: f-Element organometallic chemistry is dominated by cyclopentadienyl ligands. In contrast, isoelectronic metallole ligands with the general formula [EC₄R₄]^2-, where E is a heavier group 14 element, are rare in the f-block, particularly stannole ligands. Here, we describe the synthesis of the dimetallic stannole complexes [(η⁵-Cp^Sn)M(η⁵-Cp^ttt)]₂ (1_M ; M = Y, Gd, Dy; Cp^Sn = [SnC₄-2,5-(SiMe₃)₂-3,4-Me₂]^2-, Cp^ttt = [1,2,4-C₅ ^tBu₃H₂]^-), which form by virtue of Sn→M dative bonds. One-electron reduction of 1_M with KC₈/2.2.2-cryptand produces the mono
