The pentafluoroaryl amine (C6F5)2NH (1) reacts with AlH3·NEtMe2 to give [(C6F5)2N]AlH2·NEtMe2 (2) and [(C6F5)2N]2AlH·NEtMe2 (3). The related fluorinated-aryl amine (C6F5)(n-C4H9)NH (4) also reacts with AlH3·NEtMe2 to give [(C6F5)(n-C4H9)N]3Al·NEtMe2 (5). This latter compound undergoes ligand exchange with PMe3 or N-methylimidazole to form [(C6F5)(n-C4H9)N]3Al·PMe3 (6) and [(C6F5)(n-C4H9)N]3Al·(Me-imid) (7), respectively. The latter amine also reacts with AlMe3, affording [Me2AlN(C6F5)(n-C4H9)]2 (8).Key words: almunium, amides, pentafluorophenylamine.

AlH3-NEtMe2 反应生成 [( )2N]AlH2-NEtMe2 (2) 和 [( )2N]2AlH-NEtMe2 (3)。相关的
氟化芳基胺 ( )(n-
C4H9)NH (4) 也会与 -NEtMe2 反应,生成 [( )(n- )N]3Al-NEtMe2 (5)。后一种化合物与 PMe3 或
N-甲基咪唑发生
配体交换,分别生成 [( )(n- )N]3Al-PMe3 (6) 和 [( )(n- )N]3Al-(Me-imid) (7)。后一种胺还能与 AlMe3 反应,生成 [Me2AlN( )(n- )]2 (8)。
