| 摘 要： | 在室温条件下, 离子液体1-正丁基-3-甲基咪唑四氟硼酸盐(bmim]BF4)与水组成的混合溶剂能有效催化一系列芳醛与罗丹宁反应, 以80%～93%的产率生成相应的5-芳亚甲基-2,4-噻唑二酮. 离子液体bmim]BF4催化活性高, 反应在10～120 min内完成. 实验结果表明该法反应条件温和、产率高、反应时间短、后处理简单、离子液体可重复使用.

| Abstract: | The mixed solvent of ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate and water has efficiently promoted the synthesis of a variety of 5-arylmethylidene-4-oxo-2-thiothiazolidines from the corresponding aromatic aldehydes and rhodanine at room temperature in 80%-93% yields within 10 to 120 min. The present protocol offered several advantages including mild conditions, high yields, short reaction time, and simple work-up procedure. Moreover, the ionic liquid was reusable. |
