Palladium-catalyzed cross-coupling of phenyl, vinyl, and allyl siloxane derivatives proceeded in good to excellent yield with aryl iodides, electron-deficient aryl bromides, and allylic benzoates. Methyl and 2,2,2-trifluoroethyl siloxane derivatives can be employed in the coupling reaction. Electron-donating and -withdrawing groups are tolerated on the aryl halide without affecting the coupling. The
与芳基碘化物,缺电子的芳基溴化物和烯丙基苯甲酸酯的钯催化的苯基,乙烯基和烯丙基硅氧烷衍生物的交叉偶联均以良好或优异的收率进行。甲基和2,2,2-三氟乙基硅氧烷衍生物可用于偶联反应。给电子基团和吸电子基团在芳基卤化物上是可容忍的,而不影响偶联。概述了Stille和Suzuki联轴器的替代方案的范围和局限性。
