Abstract Poly(o‐phenyleneditelluride) 6 has been prepared by the reduction of 1,2‐bis(trichlorotelluro)benzene obtained treatment 1,2‐bis(trimethylsilyl)benzene with TeCl 2 . The NaBH 4 in ethanol solution affords sodium benzene‐1,2‐ditellurolate, which, upon methylene bromide, forms benzo‐1,3‐ditellurole 40–47% yield. Benzo‐1, 3‐ditellurole also synthesized 18–20% yeild reaction 1,2‐bis(trimethylslyl)benzene bis(trichlorotelluro)methane, subsequent product, 1,1,3,3‐tetrachlorobenzo‐1,3‐ditellurole.
