Popis: | Several ionic liquids were used for Morita–Baylis–Hillman reaction; the results show that the pyridinium ionic liquids N-ethylpyridinium tetrafluoroborate ([EPy][BF4]) and N-butylpyridinium nitrate ([BuPy][NO3]) as reaction media were efficient for DABCO-catalyzed Morita–Baylis–Hillman reaction. In short reaction time, good yields have been obtained. In addition, in the presence of ionic liquid [EPy][BF4], the hexamethylenetetramine (HMTA), a cheap tertiary amine, effectively catalyzed the Morita–Baylis–Hillman reaction. |
