| Abstract: | Fe3+-exchanged fluorotetrasilicic mica acts as a highly effective and reusable catalyst for the solventless Michael reaction of β-ketoesters with vinyl ketones under mild condition. The immobilized catalyst shows higher activity than homogeneous Fe3+ catalysts, FeCl3·6H2O and Fe(NO3)3·9H2O. |
