Diaryl ditellurides have been synthesized from aryl bromides via lithiation, tellurium insertion, and ferricyanide oxidation of the resulting lithium arenetellurolates.

assay against various types of human cancer cells. Compound 5e showed better antitumor activity than did the other oxazolidinone and selenium-containing oxazolidinone compounds. These findings have provided newsyntheticstrategies for organotellurium compounds and have shown a new perspective for the study of the biological activity of chalcogen-containing organic compounds.
method using diaryl ditelluride. Further, monotellurides were converted into corresponding tellurium cations. Next, these Lewis acidic tellurium cations were used as catalysts to synthesize 1,2-dihydroquinolines from anilines and highly regioselective creation of β-aminoalcohols from epoxides.
