  Chromatography-Free and Eco-Friendly Synthesis of Aryl Tosylates and Mesylates

  摘要：

  Two chromatography-free and eco-friendly protocols have been developed to synthesize aryl tosylates and mesylates by the tosylation and mesylation of the corresponding hydroxyarenes, respectively. These protocols are superior to other known ones regarding the simplicity, reaction time and conditions, the range of substrates, yields, and environmental friendliness.

• Cobalt-Catalyzed Cross-Coupling Reactions of Heterocyclic Chlorides with Arylmagnesium Halides and of Polyfunctionalized Arylcopper Reagents with Aryl Bromides, Chlorides, Fluorides and Tosylates

  A range of aromatic organocopper or organomagnesium compounds undergo smooth cross-coupling reactions with aryl bromides, chlorides, fluorides and tosylates, leading to polyfunctionalized aromatics or heterocycles in the presence of cobalt salts (5-7.5 mol%) as catalysts. Very mild reaction conditions are needed and, in the case of cross-coupling with organocopper compounds, Bu4NI (1 equiv) and 4-fluorostyrene (20 mol%) are essential as promoters for successful couplings.

  一系列芳香族有机铜或有机镁化合物与芳基溴、氯、氟及托烯磺酸酯进行平滑的交叉偶联反应，在钴盐（5-7.5 mol%）作为催化剂的情况下，产生多功能化的芳香族化合物或杂环化合物。反应条件非常温和，且在与有机铜化合物交叉偶联的情况下，四丁基氮化铵（1当量）和4-氟苯乙烯（20 mol%）是成功偶联所必需的促进剂。

  A toss up: A highly active palladium complex enabled the first direct arylation of heteroarenes through CH bond functionalization using tosylates or mesylates as electrophiles with ample scope.

  抛弃：高活性的钯络合物可以使用甲苯磺酸盐或甲磺酸盐作为亲电试剂，通过CH键官能化，使杂芳烃首次直接芳基化，且具有足够的范围。
