ChemInform Abstract: Vinyllithiums from Butylvinyl Tellurides and Bisvinyl Tellurides.

Abstract

The vinylic tellurides (I) are transmetallated with butyllithium (II) to generate the vinyllithium compounds (III) which react with electrophiles, e.g. the aldehydes or ketones (IV), yielding the allylic alcohols (V).
