✦ Synopsis

Poly(o-phenyleneditelluride) 6 has been prepared by the reduction of I ,2-bis(trichlorotelluro)benzene obtained by treatment of 1,2-bis(trimethylsilyI)benzene with TeC14. The reduction of 6 with NaBH4 in ethanol solution affords sodium benzene-l,2-ditellurolate, which, upon treatment with methylene bmmide, forms benzo-I ,3-ditellurole in 40-47% yield. Benzo-l,3-ditellurole has also been synthesized in 18-20% yield by the reaction of 1,2-bis(trimethylsiIyl)benzene with bis(trichlorotelluro)methane, with subsequent reduction of the product, 1,1,3,3-tetrachIorobenzo-l,3-ditellurole.
