  Palladium-catalyzed carbonylative transformation of phenols via in-situ triflyl exchangement

  摘要：

  Phenols are attractive starting materials due to their ready availability. Herein, we developed a novel method on palladium-catalyzed alkoxycarbonylation of phenols. By using commercially available Pd(OAc)(2) and PtBu center dot HBF4 as the catalyst system and aryl triflates as triflyl source to activate the other phenol, various carboxylic acid esters were prepared in moderate to good yields via Tf exchange and then O-Tf bond cleavage. Notably, phenols generated from aryl triflates after Tf transfer or other additional aliphatic alcohols can all be employed as nucleophiles to synthesize the corresponding esters.

  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
