ChemInform Abstract: Carbotelluration of Phenylacetylene

The addition of diorganyl tellurides (PhTePri and nBuTeBut) to phenylacetylene took place efficiently via a radical mechanism with a perfect regioselectivity to give corresponding vinyl tellurides. The E isomer was formed exclusively in the case of nBuTeBut, whereas PhTePri gave a E/Z mixture.
