  An Improved Catalyst System for the Pd-Catalyzed Fluorination of (Hetero)Aryl Triflates

  摘要：

  The stable Pd(0) species [(1,5-cyclooctadiene)(L.Pd)(2)] (L = AdBrettPhos) has been prepared and successfully evaluated as a precatalyst for the fluorination of aryl triflates derived from biologically active and heteroaryl phenols, challenging substrates for our previously reported catalyst system. Additionally, this precatalyst activates at room temperature under neutral conditions, generates 1,5-cyclooctadiene as the only byproduct, and leads to overall cleaner reaction profiles.

  medicine and materials science, the synthesis of biheteroaryls by cross-coupling remains challenging. We describe here a new, general approach to biheteroaryls: the Ni- and Pd-catalyzed multimetallic cross-Ullmann coupling of heteroaryl halides with triflates. An array of 5-membered, 6-membered, and fused heteroaryl bromides and chlorides, as well as aryl triflates derived from heterocyclic phenols,

  尽管它们对医学和材料科学很重要，但通过交叉偶联合成双杂芳基仍然具有挑战性。我们在这里描述了一种新的、通用的双杂芳基方法：杂芳基卤化物与三氟甲磺酸酯的 Ni 和 Pd 催化的多金属交叉 Ullmann 偶联。一系列 5 元、6 元和稠合杂芳基溴化物和氯化物，以及衍生自杂环酚的芳基三氟甲磺酸酯，被证明是该反应中可行的底物（62 个示例，平均产率为 63 ± 17%）。这种方法对双杂芳基的普遍性在 10 μmol 规模的 96 孔板格式中得到进一步证明。一组 96 种可能的产品在一组条件下提供了 >90% 的命中率。此外，可以使用配体、添加剂和还原剂的单个“工具箱板”快速优化低产率组合。
