Novel Buchwald–Hartwig aminations of aryl fluorosulfonates using a catalytic amount of Pd(PPh₃)₄ in the presence of Cs₂CO₃ are described. From these reactions, a variety of biaryl amines were obtained in moderate to good yields. This system allows for the efficient amination of aromatic groups containing electron‐rich as well as electron‐poor functional groups. Aryl fluorosulfonates could be applied as alternative cross‐coupling partners to aryl halides in palladium‐catalyzed aminations.

Pd（PPh3）4催化芳基氟磺酸的布赫瓦尔德-哈特维奇氨基化

描述了在Cs ₂ CO ₃存在下使用催化量的Pd（PPh ₃）₄进行的新颖的Buchwald-Hartwig芳基氟磺酸酯胺化反应。从这些反应中，以中等至良好的产率获得了各种联芳基胺。该系统可以有效地胺化含富电子基团和贫电子官能团的芳族基团。氟磺酸芳基酯可以用作钯催化胺化过程中芳基卤化物的交叉偶联替代物。
