A FACILE STEREOSELECTIVE SYNTHESIS OF (E,E)-CONJUGATED DIENYL TELLURIDES BY PALLADIUM-CATALYZED CROSS-COUPLING REACTION
摘要:
A cross-coupling reaction of (E)-beta -bromovinyl tellurides with alkenes in the presence of catalytic amount of Pd(OAc)(2) and PPh3, AgCO3 as a base carried out in acetonitrile to produce (E,E)-conjugated dienyl tellurides.

Reaction of aryltellurium tribromides with alkynes in methanol affords (E)-β-bromovinyl aryltellurium dibromides and in benzene gives the (Z)-isomer, which can be reduced by sodium borohydride to yield (Z) or (E)-β-bromovinyl tellurides respectively.
