A general procedure for the synthesis of aryl thioethers and aryl selenides in one-pot through sequential iridium-catalyzed C–H borylation and copper-promoted C–S and C–Se bond formation is described. Functional groups including chloro, nitro, fluoro, trifluoromethyl, and nitrogen-containing heterocycles were all tolerated under the reaction conditions. Importantly, not only aryl thiols and selenides
描述了通过顺序铱催化的 C-H 硼化和铜促进的 C-S 和 C-Se 键形成在一锅中合成芳基硫醚和芳基硒化物的一般程序。在反应条件下,包括氯、硝基、氟、三氟甲基和含氮杂环在内的官能团都可以耐受。重要的是,不仅芳基硫醇和硒化物而且它们的烷基类似物都是合适的偶联伙伴,并且以高产率和高间位区域选择性获得了产物。
