greenly by the cascade aldol/Michael/additionreaction of aromatic aldehyde, acetophenone, and NH4OAc (1:2:excessive) in ionic liquid [BmIm][BF4] without any catalyst. The results of their catalyzed activity on two simple Diels–Alderreactions indicated that this kind of compound containing a poly aryl ring can be used as an effective catalyst on the Diels–Alderreaction. This method, because of its environmental
