Poly 1,4-phenylene ditellurium

Dilithium or disodium areneditellurolates were alkylated with methyl iodide3, dimethyl sulfate4, or diethyl sulfate4. The areneditellurolates were prepared from the corresponding dibromides and tert.-butyl lithium in tetrahydrofuran and treatment of the resulting mixture with powdered tellurium3, or by the reduction of poly(l,4-phenylene ditellurium) with sodium borohydride in ethanol/benzene4. 

Poly(l,4-phenylene Ditellurium)1 Under nitrogen, a solution of 1 mol of 1,4-dibromobenzene is cooled to — 15° with stirring, a solution of 22 mol of butyl lithium in hexane is added dropwise followed by 1 mol of finely ground tellurium, and the mixture is stirred at 20° until all of the tellurium has dissolved. To this mixture is added 2 mol of butyl lithium followed by 1 mol of powdered tellurium. When all of the tellurium has dissolved, 2 mol of water and then 2 mol of triethylaminc arc added. The resultant tellurolate is oxidized by addition of an aqueous solution of potassium hexacyanoferrate(Ill) yield 54% reddish-brown, amorphous powder.
