Trihalotellurium Compounds of Hydroquinone Dimethyl Ether

Abstract

Tellurium(IV) chloride when reacted with hydroquinonedimethyl ether yield the aryltellurium trichloride, 1,4-(MeO)₂C₆H₃]TeCl₃. This trichloride undergoes halogen-exchange reactions to give corresponding tribromide and triiodide. Conductance and cryoscopic measurements reflect their electrolyte type behaviour in solution. ¹H NMR spectral study confirms the linkage of trichloro tellurium group to a carbon atom of aromatic ring which is ortho to one of the methoxy groups. Far IR spectra reflect their polymeric nature in the solid state.
