  A catalyst system for the Stille cross-coupling reactions of aryl mesylates and tosylates is reported. Using the combination of Pd(OAc)2, XPhos, and CsF in t-BuOH an array of aryl and heteroaryl sulfonates were successfully employed in these reactions. Morever, heteroarylstannanes, such as furyl, thiophenyl, and N-methylpyrrole, which are often prone to decomposition, were efficiently coupled under

  报道了用于甲磺酸芳基酯和甲苯磺酸酯的 Stille 交叉偶联反应的催化剂体系。在 t-BuOH 中使用 Pd(OAc)2、XPhos 和 CsF 的组合，在这些反应中成功地使用了一系列芳基和杂芳基磺酸盐。此外，通常易于分解的杂芳基锡烷，例如呋喃基、噻吩和 N-甲基吡咯，在这些条件下可以有效地偶联。锡烷偶联伙伴上的邻位取代耐受良好；然而，芳基磺酸酯上邻位取代基的存在大大降低了这些反应的效率。

  aryl carboxyl radicals favor strongly competitive addition to arene pathways. Herein, we demonstrate a solution to this challenge: a charge-transfer complex of aryl carboxylate via n-π∗ and π-π interactions induces chemoselective decarboxylation to aryl radicals for general functionalization. Presumably, the triplet complex significantly slows the rate of second-order aryl carboxyl radical addition to

  芳基自由基被用作芳基化的多功能中间体，用于制备天然产物、药物和功能材料。由于芳基羧酸的广泛可用性和稳定性以及温和的条件，光诱导芳基羧酸直接脱羧为芳基自由基被认为是有吸引力的。然而，直接脱羧已被证明非常具有挑战性，因为芳基羧基有利于芳烃途径的强烈竞争性加成。在此，我们展示了应对这一挑战的解决方案：通过 n-π* 和 π-π 相互作用的芳基羧酸酯的电荷转移复合物诱导芳基自由基的化学选择性脱羧，以实现一般功能化。据推测，三重态复合物显着减慢了二阶芳基羧基加成至芳环的速率，导致选择性脱羧为芳基自由基。我们的研究应该通过使用易于获得且稳定的芳基羧酸，以及用于选择性自由基转化的新光氧化还原催化模式，在温和条件下激发各个领域的大量芳基化反应。
