A novel palladium-catalyzed sulfination of aryl and heteroaryl halides is described. This reaction operates under mild conditions and provides access to a wide range of aryl and heteroaryl sulfinates, a useful and versatile class of synthetic intermediates. Capitalizing on this sulfination reaction, one-pot protocols allowing direct access to sulfones and sulfonamides have also been developed. The
描述了新颖的钯催化的芳基和杂芳基卤化物的硫化。该反应在温和的条件下进行,并提供了广泛的芳基和杂芳基亚磺酸盐,这是一种有用且用途广泛的合成中间体。利用这种硫化反应,还开发了一种一锅法,可以直接使用砜和磺酰胺。这些转化的实用性通过药物万艾可类似物的平行合成得到了说明。
