离子液体系中催化环己酮肟重排制己内酰胺

摘要

发现由室温离子液体1－丁基－3－甲基咪唑三氟乙酸盐、正丁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，具有不再用有机溶剂、反应副产物少等特点；并考察了含磷化合物用量和反应温度对反应的转化率和选择性的影响。%Beckmannrearrangement of cyclohexanone oxime has been studied in catalytic med ium composed of ionic liquids and phosph orous－containing compounds such as phosp horous pentachloride without the presenc e of any other organic solvent．The trans formation was found to proceed very effe ctively under mild conditions．The influe nce of the amount of phosphorous－contain ing compounds and the reaction temperatu re on the reaction was also investigated ．
