A highly efficient palladium-catalyzed direct desulfitative arylation of azoles at C2-position has been developed using sodium arylsulfinates as aryl sources. Azoles including benzoxazoles, benzothiazoles, oxazoles, thiazoles, and 1,3,4-oxadiazoles reacted with sodium arylsulfinates smoothly to generate the corresponding products in good to excellent yields, and various substitution patterns were tolerated
使用芳基次磺酸钠作为芳基来源,已经开发出了一种高效的钯催化的C2位的吡咯直接脱硫芳基化反应。包括苯并恶唑,苯并噻唑,恶唑,噻唑和1,3,4-恶二唑的唑与芳基亚磺酸钠顺利反应生成相应的产物,收率良好至优异,并且在反应中可以采用各种取代方式。
