  developed a sustainable protocol for the synthesis of aromatic esters by a carbonylative method using di‐μ‐chlorobis [5‐hydroxy‐2‐[1‐(hydroxyimino‐ĸN) ethyl] phenyl‐ĸC] palladium (II) dimer (1) catalyst in PEG‐400 as a greener and recyclable solvent. The reaction is carried out at room temperature using CO in a balloon. Good to excellent yield of various esters can be synthesize using this protocol.

  在本报告中，我们开发了一种可持续的方案，该方案使用二μ-氯双[5-羟基-2- [1-（羟基亚氨基-N）乙基]苯基-C]钯（II）通过羰基化方法合成芳族酯）二聚体（1）在PEG-400中作为绿色和可回收溶剂的催化剂。该反应在室温下在气球中使用CO进行。使用该方案可以合成各种酯的良好或极好的收率。CO部分的直接插入导致高原子和阶梯经济性。与以前的协议相比，这种无膦的芳族酯合成方法具有较高的周转率（TON）和周转频率（TOF）。开发的方法具有使用常规钯前体的高转化率和选择性的替代途径。使用二乙醚作为溶剂可以轻松分离催化剂体系和产物。Pd / PEG-400系统可以重复使用多达五个连续周期，而不会损失其活性和选择性。

  mediate ester synthesis from carboxyl acids and alcohols/phenols. Carboxylic acids are transformed to trifluoromethyl ester and acyl fluoride activated species that interact with each other. The broad substrate scope and late-stage application of this method are demonstrated. This study opens up new opportunities to develop interesting reactions using Cu(III)–CF3 compounds without transferring a CF3

  Cu( III )–CF 3化合物在本文中被报道为新型偶联剂，可介导羧酸和醇/酚的酯合成。羧酸转化为三氟甲酯和酰基氟活化物质，它们相互作用。证明了该方法的广泛底物范围和后期应用。这项研究开辟了新的机会，可以使用 Cu( III )–CF 3化合物开发有趣的反应，而无需将 CF 3基团转移到产品中。
• Gold-Catalyzed C–O Cross-Coupling Reactions of Aryl Iodides with Silver Carboxylates
  作者：Guifang Chen、Bo Xu

  DOI：10.1021/acs.orglett.3c02254

  日期：2023.9.1

  We have developed a C–O cross-coupling reaction of (hetero)aryl iodides with silver carboxylates via a AuI/AuIII catalytic cycle. The transformation featured exclusive chemoselectivity and moisture/air insensitivity. Aromatic and aliphatic (including primary, secondary, and tertiary) silver carboxylates are all suitable substrates. Moreover, this protocol worked well intermolecularly and intramolecularly

  我们开发了（杂）芳基碘化物与羧酸银通过 Au I /Au III催化循环进行的 C-O 交叉偶联反应。该转化具有独特的化学选择性和湿气/空气不敏感性。芳香族和脂肪族（包括伯、仲和叔）羧酸银都是合适的底物。此外，该方案在分子间和分子内均表现良好。最重要的是，无论底物的电子效应和空间位阻如何，都获得了良好的产率。
