Palladium-promoted homocoupling reaction of vinyl- and polyenylsilanes in aqueous conditions has been investigated. The reaction is catalyzed by PdCl2 in the presence of the reoxidizing system CuCl2/LiCl and occurs at room temperature in aqueous solutions containing nonionic amphiphiles. Symmetrically α,ω-disubstituted stereodefined all-trans polyenes have been obtained in mild conditions and in good yields (65–87%), higher than those previously reported for the same reactions carried out in methanol or HMPA. A comparison between two commercially available surfactants, Triton X-100 and PTS, has been performed.

Abstract

Palladium-promoted homocoupling reaction of vinyl- and polyenylsilanes in aqueous conditions has been investigated. The reaction is catalyzed by PdCl2 in the presence of the reoxidizing system CuCl2/LiCl and occurs at room temperature in aqueous solutions containing nonionic amphiphiles. Symmetrically α,ω-disubstituted stereodefined all-trans polyenes have been obtained in mild conditions and in good yields (65–87%), higher than those previously reported for the same reactions carried out in methanol or HMPA. A comparison between two commercially available surfactants, Triton X-100 and PTS, has been performed.
