【摘要】 发现由室温离子液体正丁基吡啶氟硼酸盐,异丁基吡啶氟硼酸盐,正戊基吡啶氟硼酸盐,正辛基吡啶氟硼酸盐等和含磷化合物组成的催化体系,可以高效地实现对环己酮肟重排制己内酰胺的反应,此方法具有不再用有机溶剂,反应副产物少等特点,并考察了不同的离子液、不同磷化合物催化剂、离子液的用量、反应温度、反应时间等对反应的转化率和产物分布的影响,以寻找出一最适宜的反应条件。更多还原

【Abstract】 Beckmann rearrangement of cyclohexanone oxime has been studied in catalytic medium composed of ionic liquids and phosphorous-containing compounds such as phosphorous pentachloride without the presence of any other organic solvent. The transformation was found to proceed very effectively under mild conditions.The catalytic effect of different phosphorous-containing compounds,the amount of ionic liquids, the reaction temperature on the reaction and the reaction time was also investigated.更多还原
