摘要：

Vinylic tellurides were synthesized by the addition of diorganyl tellurides to acetylenes in the presence of a radical initiator or by visible light irradiation. Vinylic tellurides underwent transmetalation by the reaction with triethylaluminium or diethylzinc to form the corresponding vinylmetal reagents with retention of the double bond configuration. Oxidation of vinylic tellurides formed by carbotelluration reactions followed by pyrolysis gave internal acetylenes in good yields.
