Methyl methyltelluroethynyl

Disodium acetylide, prepared from sodium and acetylene in liquid ammonia, was reacted first with tellurium and then with methyl iodide to give methyl methyltelluroethynyl tellurium4. 

Dilithium ethyneditellurolate was obtained in reactions of monolithium acetylide or of dilithium acetylide with tellurium in tetrahydrofuran containing 1,2-diaminoethane (DAE). The ditellurolate was reacted with methyl iodide to produce methyltelluroethynyl methyl telluride in good yields based on tellurium employed. The surprising formation of the ditellurolate from the monolithium acetylide was explained by the disproportionation of monolithium acetylide into dilithium acetylide and acetylene. ...
