Abstract
Diorganyl tellurides (RTeR′) undergoes exchange reaction by the treatment with organometallic reagents of alkali and organoalkaline-earth metals (M˭Li, Na, K, MgX and CaX) in a fashion that thermodynamically more stable carbanions are formed, which then react with carbonyl compounds to give corresponding addition products in good yields. The scope and limitation of the exchange reactions are also discussed.Keywords
