sulfinate salts, and, more importantly, providing access to electron-rich pyridine substrates. Sulfonylated pyridines were synthesized in moderate to excellent yields, with a wide scope of substituted pyridines and sulfinate salts as starting materials, by an iron-catalyzed SNAr reaction. This new methodology exhibits advantages for the synthesis of these useful substrates, such as the use of a readily
摘要 磺酰化吡啶通过铁催化的S N Ar反应以中等至优异的产率合成,并以广泛范围的取代吡啶和亚磺酸盐为起始原料。这种新方法显示出合成这些有用底物的优点,例如使用易于获得的廉价催化剂,防止亚磺酸盐歧化,更重要的是,提供了接触富电子吡啶底物的途径。 磺酰化吡啶通过铁催化的S N Ar反应以中等至优异的产率合成,并以广泛范围的取代吡啶和亚磺酸盐为起始原料。这种新方法显示出合成这些有用底物的优点,例如使用易于获得的廉价催化剂,防止亚磺酸盐歧化,更重要的是,提供了接触富电子吡啶底物的途径。
