Artykuł
The coupling of organosilanes and different olefins was performed efficiently in the presence of anioniccomplexes, [CA]2[PdX4] and [CA]2[Pd2X6], where CA = imidazolium or pyridinium cation. The reactionproceeds according to a Pd(II)-mediated pathway, and Cu(OAc)2acts as the re-oxidant of Pd(0) formedduring the catalytic process. High product yields were obtained for differently substituted olefins at 80◦Cin 4 h. Styrylsilanes reacted in the same conditions giving unsymmetrical 1,3-dienes.
