The study focuses on the synthesis and characterization of tetramethyltetratellurafulvalene (TMTTeF) and its electrochemical properties. TMTTeF was synthesized using a method involving acetylene, hexamethylditin, n-BuLi, and elemental tellurium, with tetrachloroethylene as a reactant in the final step. The compound was purified through chromatography and characterized by spectroscopic methods, including mass spectrometry and NMR spectroscopy. The electrochemical data, obtained by cyclic voltammetry, revealed that TTeF exhibits two reversible one-electron oxidations, with an ionization potential between that of tetrathiafulvalene (TTF) and tetraselenafulvalene (TSF). The study also discusses the presence of a six-membered ring isomer in the crude TTeF, identified through an irreversible oxidation peak in the cyclic voltammogram. The research aims to explore the potential of TTeF in forming organic metals and to make this synthesis available to the broader scientific community for further exploration of its solid-state properties.
