Phosphono-1,3-dienyl compounds 2 can be prepared by palladium cross-coupling reaction of β-phenyltelluro-vinylphosphonates or -vinylphosphine oxides with alkenes in the presence of a catalytic amount of PdCl2 and AcOAg as reoxidant agent at room temperature. The coupling reaction is stereospecific and the compounds 2 were obtained in good yields with total retention of configuration.

Reactions of organyl tellurols generated in situ from ditellurides and alkynes bearing electron-stabilizing groups such as the phosphonyl and sulfonyl groups gave the β-organyltelluro vinylphosphonates or vinyl sulfones in high yield, which are followed by transmetallation by organometallic reagents.

Stereoselective addition of sodium organyl chalcogenolates to alkynylphosphonates: Synthesis of diethyl 2-(organyl)-2- (organochalcogenyl)vinylphosphonates
Braga, Antonio L.,Alves, Elenilson F.,Silveira, Claudio C.,De Andrade, Leandro H.
, p. 161 - 163 (2007/10/03)
Organyl thiolate, selenolate or tellurolate anions reacted with alkynylphosphonates 1 to give diethyl 2-(organyl)2- (organochalcogenyl)vinylphosphonates [β-organochalcogenyl vinylphosphonates] 2 in satisfactory yields. The reaction was stereoselective, gi
