highlighted in the palladium‐catalyzed aminocarbonylation, alkoxycarbonylation, carbonylative Sonogashira coupling, and carbonylative Suzuki–Miyaura coupling of aryl halides. A variety of amides, esters, (hetero)aromatic ynones, and bis(hetero)aryl ketones were synthesized in good‐to‐excellent yields in a one‐pot fashion.
羧基-MIDA-硼酸酯的应用(MIDA = N-甲基亚氨基二乙酸)作为各种钯催化转化的原位CO替代物进行了描述。先前曾证明,羧基MIDA硼酸酯是合成硼酸化杂环化合物的长凳稳定的含硼结构单元。本研究表明,羧基-MIDA-硼酸酯除了可用作杂环合成的前体外,它还是一种出色的原位CO替代物,可耐受胺,醇和碳基亲核试剂等反应性功能。在钯催化的氨基羰基化,烷氧基羰基化,羰基化的Sonogashira偶联和芳基卤化物的羰基化的Suzuki-Miyaura偶联中,突出了其广泛的官能团相容性。各种酰胺,酯,(杂)芳族炔酮
