A Well‐Defined Dinuclear Telluronic Acid [RTe(μ‐O)(OH)₃]₂

Abstract

Two for Te: The ditelluronic acid 3 is the first heavy congener of sulfonic and selenonic acids and is obtained by the O2 oxidation of the tellurinate 2 in the presence of [18]crown-6. Compound 2 is prepared by the reaction of the ditellurinic acid 1 with NaH. The direct oxidation of 1 to 3 using strong oxidants, such as H2O2, KMnO4, and NaIO4 failed.
