Cyclometallated tellurium complexes of the monoanionic ligand 2-(3-thienyl)pyridine have been synthesised via organolithium compounds. Reaction of RLi (where R=3-(2-py)-2-C4H2S) with elemental tellurium followed by oxidative workup afforded a novel ditelluride of the formula R2Te2. Reactions of ditelluride with bromine and thionyl chloride gave the corresponding aryltellurium tribromide and trichloride. Reduction of the trichloride with a stoichiometric amount of hydrazine hydrate gave the organyltellurium(II) chloride. The derivatives have been characterized by 1H NMR, 13C NMR, UV/Vis and MS techniques.
