catalytic system for the aerobic oxidation of primary amines into corresponding oximes has been developed, with 3‐methyl‐4‐oxa‐5‐azahomoadamantane as catalyst, acetaldoxime as co‐catalyst and water as solvent. This process, which uses oxygen (O2) as an economic and green oxidant and water as a green solvent, tolerates a wide range of substrates, affording the target oximes in moderate to excellent
已开发出一种简单有效的催化系统,用于将伯胺有氧氧化为相应的肟,其中3-甲基-4-氧杂-5-氮杂十二烷金刚烷为催化剂,乙醛肟为助催化剂,水为溶剂。该方法使用氧气(O 2)作为经济的绿色氧化剂,使用水作为绿色的溶剂,可耐受多种底物,从而以中等至极好的收率提供目标肟。结果发现,使用3-甲基-4-氧杂-5-氮杂十二烷金刚烷可以实现高选择性,而E型肟是唯一检测到的产物。提出了该催化过程的可能机理。
