Silacarboxylic acids have been demonstrated to be easy to handle, air-stable carbonmonoxide precursors. Different silacarboxylic acids were synthesized from the corresponding chlorosilanes and carbon dioxide, and their decarbonylation, upon treatment with an array of activators, was evaluated. The release of CO from crystalline MePh(2)SiCO(2)H proved to be highly efficient, and it was successfully
硅羧酸已被证明是易于处理、空气稳定的一氧化碳前体。从相应的氯硅烷和二氧化碳合成了不同的硅羧酸,并评估了它们在用一系列活化剂处理后的脱羰。从结晶 MePh(2)SiCO(2)H 中释放 CO 被证明是高效的,并且它成功地应用于使用接近化学计量数量的一氧化碳前体的钯催化羰基化偶联的选择。最后,证明了 MePh(2)Si(13)CO(2)H 的合成及其在两种生物活性化合物的羰基标记中的应用。

The use of t-Bu3P as a ligand dramatically improved the generality of the double carbonylation of aryliodides, and Mo(CO)6 was also found to be effective as a CO source in the system.
