LITHIUM ORGANYL-POLYCHALCOGENOLATES

Lithium organyl-selenolates, RSeLi or tellurolates, RTeLi insert further equivalents of chalcogens with formation of selenyl-selenolates, RSeSeLi or tellurenyl-tellurolates, RTeTeLi (R=Me, n-Bu, s-Bu, t-Bu, Ph).Mixed anions are only formed if the chalcogen insertion order corresponds with an increase of electronegativity, i.e.: RTeSeLi, RTeSLi, RSeSLi and n-BuTeSeSLi.All species have been characterized by 77-Se and 125-Te NMR-spectroscopy.Tellurenyl-tellurolates and tellurenyl-selenolates are stable at room temperature, selenyl-selenolates and chalcogenyl-thiolatesdisproportionate.The chemical integrity of the chalcogenyl-chalcogenolates was checked by methylation with methyl triflate.The formed organyl-methyl-dichalcogenides exhibit symmetrization equilibria that are also obtained by mixing the symmetric conpounds.Oxidation of tellurenyl-selenolates affords di(organyl-tellurenyl) selenides, (RTe)2Se (R=Me, n-Bu, t-Bu, Ph, p-MeC6H4, 2-thienyl) and (RTe)2Se2 for R=(Me3Si)3C.In solution (RTe)2Se are in equilibrium with R2Te2 and (RTe)2Se2.
