Palladium-catalyzed C-H activation/C-O bond-forming reactions have emerged as attractive tools for organic synthesis. Typically, these reactions require strong chemical oxidants, which convert organopalladium(II) intermediates into the PdIII or PdIV oxidation state to promote otherwise challenging C-O reductive elimination. However, previously reported oxidants possess significant disadvantages, including
钯催化的 CH 活化/CO 键形成反应已成为有机合成的有吸引力的工具。通常,这些反应需要强化学氧化剂,将有机钯 (II) 中间体转化为 PdIII 或 PdIV 氧化态,以促进其他具有挑战性的 CO 还原消除。然而,先前报道的氧化剂具有显着的缺点,包括原子经济性差、成本高和形成不需要的副产物。为了克服这些问题,我们报告了一种电化学策略,该策略利用 PdII 的阳极氧化与各种氧阴离子偶联伙伴诱导选择性 CO 还原消除。
