摘要

在阴离子配合物[CA]2[PdX4]和[CA]2[Pd2X6]的存在下,有机硅烷与不同的烯烃进行了有效的偶联,其中CA =咪唑或吡啶阳离子。反应根据Pd(II)介导的途径进行,Cu(OAc)2作为催化过程中生成的Pd(0)的再氧化剂。不同取代的烯烃在80℃下反应4 h得到了较高的产率。苯乙烯基硅烷在相同条件下反应得到不对称的1,3-二烯。

Efficient functionalization of olefins by arylsilanes catalyzed by palladium anionic complexes

Efficient functionalization of olefins by arylsilanes catalyzed by palladium anionic complexes

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