摘要
Ketones and β-diketones were nitrosated and converted to their corresponding aoximinoketones using task-specific ionic liquids, l-（4-nitritobutyl）-3-methylimidazolium chloride, IL-ONO, and 1-butyl-3-methylimidazolium nitrite at room temperature. The results from two ionic liquids are comparable and showed that these IL＇s are effective nitrosonium sources for the preparation of oximinoketones. The protocol is rapid, the yields are excellent, and the method is simple.
