Methodologies for the totalcontrol on the synthesis of E, Z or 1,1-dissubstituted vinylictellurides are described. Tellurobutadienes bearing the butyltellurium moiety at carbon 2 or at carbon 1 with E or Z configuration at the tellurium containing double bond were also obtained. Addition of diisobutylaluminum butyltellurolate to terminal alkynes resulted in the formation of 1-(butylteluro)-1-(organyl)
