• Aromatic substitution and dealkylation by alkanetellurolate Anions

  Under the action of alkanetellurolate anion phenyl halides undergo aromatic substitution followed by dealkylation of the alkyl phenyl telluride thus formed. The generated benzenetellurolate anion can be either alkylated or oxidized to diphenyl ditelluride, or added to acetylene. Butyl methyl telluride and selenide are demethylated by methanechalcogenolate anions.

• Tellurium in Organic Synthesis. Preparation of <i>Z</i>-Vinylic Cuprates from <i>Z</i>-Vinylic Tellurides and Their Reaction with Enones and Epoxides

  Z-Vinylic tellurides, obtained with 100% stereoselectivity by the hydrotelluration of acetylenes, are easily transformed into Z-vinylic higher order cyanocuprates by reaction with preformed Me(2)Cu(CN)Li-2, n-Bu(2)Cu(CN)Li-2, or n-Bu(2-Th)Cu(CN)Li-2, with total retention of the double-bond configuration. The resulting vinylic higher order cyanocuprates react with unhindered enones to give the corresponding 1,4-addition products in good yields. Reaction of the vinylic higher order cyanocuprates with monosubstituted epoxides at 0 degrees C gives the homoallylic alcohols resulting from the attack to the less-substituted carbon atom, while the disubstituted epoxides failed to react. Allylic epoxides react at -78 degrees C with the vinylic higher order cyanocuprates to give mixtures of 1,2- and 1,4-opening products, the 1,4-product predominating. In all cases the double-bond configuration of the original vinylic telluride was preserved. The vinylic cuprates derived from simple vinylic tellurides and conjugated 1-telluroenynes react with epoxides at 0 degrees C, while vinylic cuprates derived from conjugated 1-tellurodienes required the addition of 1 equiv of BF3 . Et(2)O to give the homoallylic alcohols on reaction with epoxides. The opening of optically pure epoxides through tellurium/copper transmetalation is stereospecific, giving one single stereoisomer of the corresponding homoallylic alcohol.
