摘要：

Olerins conjugated to electron-withdrawing groups (e.g. CHO, RCO, CO2R, CN) react rapidly with alkylselenols and tellurols generated in situ to give the corresponding beta-chalcogeno aldehydes, ketones, esters and nitriles. beta-Telluroketones are transformed into beta-telluroketals, which are beta-lithiocarbonyl synthons.
