An efficient protocol has been developed for the carbonylative Hiyama coupling of aryl halides using the cesium fluoride as a promoter by palladium-catalyzed in NMP. This protocol was applied to a wide variety of functionalized and hindered aryl iodides and bromides with arylsilanes, to afford the desired biaryl ketones in good to excellent yields.
已经开发了一种有效的方案,用于将氟化铯作为促进剂,通过钯在NMP中催化,对芳基卤化物进行羰基化Hiyama偶联。该方案适用于各种带有芳基硅烷的官能化和受阻的芳基碘化物和溴化物,以良好至极佳的收率提供所需的联芳基酮。
