应用

类似于第三代(G3)预催化剂的第四代(G4)Buchwald预催化剂,不同之处在于联苯主链上的氨基被甲基化。这种修饰有助于防止在使用第三代预催化剂时所发现的局限性。它是空气、水分和热稳定的,在普通有机溶剂中显示出良好的溶解性。

In Pd-catalyzed C-N cross-coupling reactions, α-branched secondary amines are difficult coupling partners and the desired products are often produced in low yields. In order to provide a robust method for accessing N-aryl α-branched tertiary amines, new catalysts have been designed
