Palladium(II)‐catalyzed arylation of arenes with aryl boronic acids and a free amine as directing group in aqueous medium has been developed. High reactivity and chemoselectivity for the formation of carbon–carbon bonds were achieved by the use of soluble silver salts. The addition of water is crucial to improve the arylation yield.
已经开发了钯(II)催化芳烃与芳基硼酸和游离胺作为芳基在水性介质中的芳基化反应。通过使用可溶性银盐,可以实现形成碳-碳键的高反应活性和化学选择性。加水对于提高芳基化产率至关重要。
