}] [R = C6F5 (4a), 2,6-Me2C6H3 (4b)]. When the substituent on the nitrogen is 2,6-Me2C6H3, it is possible to isolate the bis(phenoxido-imino) hydride [AlH3,5-tBu2–2-(O)C6H2CH=N–2,6-Me2C6H3}2] (3) if the reaction is performed at low temperature. Compound 4a is converted in wet toluene at room temperature readily and quantitatively into the aluminoxane [(Al3,5-tBu2–2-(O)C6H2CH=NC6F5}3,5-tBu2–2-(O
AlH3·NEtMe2 与
水杨醛亚胺反应 3,5-tBu2–2-(OH)C6H2CH=NR [R =
C6F5 (1a), 2,6-Me2C6H3 (1b); 0.5 equiv.] 得到双
