【摘要】 氧化反应是有机化学课程中需掌握的重要知识点，然而，有机化学实验教材中环己醇氧化为环己酮，所用的重铬酸钠和浓硫酸组合，毒性大，腐蚀性强，有些学校取消了这个氧化实验，从而导致理论与实验之间的脱节。为了弥补这个环节，开发了一种新的氧化方法，使用4-乙酰氨基-2,2,6,6-四甲基-1-氧杂哌啶四氟硼酸盐(巴比特盐)将环己醇清洁地氧化成环己酮。可作为一种安全、方便和绿色的反应用于本科教学实验，并且可以在标准的3～4 h内完成实验。更多还原

【Abstract】 Oxidation reactions are an essential part of Organic Chemistry curriculum for undergraduates, however, the combination of sodium dichromate and concentrated sulphuric acid used in the oxidation of cyclohexanol to cyclohexanone in university Organic Chemistry textbooks is so toxic and corrosive that some schools have cancelled this oxidation experiment, resulting in a disconnect between theory and the experimental learning environment. To bridge this gap, a new oxidation method was developed for the clean oxidation of cyclohexanol to cyclohexanone using commercially available 4-acetamido-2,2,6,6-tetramethyl-1-oxapiperidine tetrafluoroborate(Babbitt salt). It can be used as a safe, convenient and green oxidation for undergraduate teaching experiments and can be completed in a standard 3～4 hour cycle更多还原
