palladium-catalyzed C–O bond formation method for the synthesis of silacarboxylates by silacarboxylic acids with a broad range of aryl iodides and iodo-N-heterocycles is reported. Electron-deficient, electron-rich, and sterically hindered aryl iodides were well-tolerated to furnish the corresponding aryl silacarboxylates in moderate to excellent yields. Active functional groups, such as −NH2, −CHO, and allyl–, showed
报道了第一种钯催化的C–O键形成方法,该方法通过具有广泛范围的芳基碘化物和碘代-N-杂环的硅烷基羧酸合成硅烷基羧酸盐。充分耐受电子不足,电子富集和空间受阻的芳基碘化物,以中等至极好的收率提供相应的芳基硅烷羧酸盐。活性官能团,例如-NH 2,-CHO和烯丙基-,即使在大规模合成中也显示出良好的耐受性。还证明了两次和三次酯化是有效的。
