A silver‐triggered heterogeneous Pd‐catalyzed oxidative carbonylation has been developed. This heterogeneous process exhibits high efficiency and good recyclability, and was utilized for the one‐pot construction of polycyclic compounds with multiple chiral centers. AgOTf was used to remove chloride ions in the heterogeneous catalyst Pd‐AmP‐CNC, thereby generating highly active PdII, which results in
开发了银触发的异相钯催化氧化羰基化反应。该非均相过程表现出高效率和良好的可回收性,可用于具有多个手性中心的多环化合物的一锅法构建。AgOTf被用来去除多相催化剂Pd-AmP-CNC中的氯离子,从而生成高活性的Pd II,从而实现多相催化体系的高效率。
