nitrosated and converted to their corresponding α‐oximinoketones using task‐specific ionic liquids, 1‐(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
使用任务专用离子液体,1-(4-硝基丁基)-3-甲基咪唑鎓氯化物,IL-ONO和1-丁基-3-甲基咪唑鎓亚硝酸盐将酮和β-二酮亚硝化并转化为相应的α-肟基酮温度。两种离子液体的结果具有可比性,表明这些IL是制备肟亚酮的有效硝化源。该方案快速,收率极好且方法简单。
