Li(OHCH2CH2NH2)(CF3OAC): A novel and homogeneous acidic ionic liquid catalyst for efficient synthesis of 2-amino-4H-chromene derivatives
The ionic liquid Li(OHCH2CH2NH2)(CF3OAC) was found to efficiently catalyze the three-component reaction between different enols, aldehydes, and malononitrile , leading to rapid synthesis of 2-amino-4H-chromene derivatives in fairly high yields. The catalyst is easily prepared, highly stable, simple to handle and recycled for several times without significant loss of activity. The method is simp...

متن کاملCe-ZSM-11 Zeolite: An Efficient Heterogeneous Catalyst for One-Pot Synthesis of 4H-Pyran Derivatives
ZSM-11 zeolite was synthesized by hydrothermal treatment and cerium ion was incorporated by the ion exchange method. The catalytic activity of cerium modified ZSM-11 zeolite was tested for the one-pot synthesis of 4H-pyran derivatives by cyclocondensation of aromatic aldehyde, malononitrile, and ethyl acetoacetate. The synthesized catalyst was characterized by Po...
