微波辐射下酸性离子液体促进氧杂蒽二酮类衍生物的合成

Acidic ionic liquid promoted synthesis of xanthenedione derivatives under microwave irradiation

以芳香醛和1,3-环己二酮或5,5-二甲基-1,3-环己二酮为原料,在微波辐射条件下,酸性离子液体[bmim]HSO4作催化剂,合成了一系列的氧杂蒽二酮类衍生物。该方法具有操作简便、反应时间短、产率较高、反应体系对环境友好、催化剂可回收重复使用等优点。

A series of xanthenedione derivatives were synthesized via the reaction of aromatic aldehydes with 1,3-cyclohexanedione or 5,5-dimethy-1,3-cyclobexanedione promoted by acidic ionic liquid （ [ bmim ] HSO4 ） under microwave irradiation. This proposed method could be easily carried out with short reaction duration and high yield and was environmentally friendly. The catalyst could be reusable.
