Polyaniline Supported FeCl3: An Effective Heterogeneous Catalyst for Biginelli Reaction

Polyaniline supported FeCl 3 is prepared and tested as an efficient heterogeneous Lewis acidic catalyst for the Biginelli reaction. The catalyst PANI–FeCl 3 shows excellent activity in the synthesis of dihydropyrimidinones from aldehydes in the three component reaction with urea and β-keto esters or...

Description
Summary:Polyaniline supported FeCl 3 is prepared and tested as an efficient heterogeneous Lewis acidic catalyst for the Biginelli reaction. The catalyst PANI–FeCl 3 shows excellent activity in the synthesis of dihydropyrimidinones from aldehydes in the three component reaction with urea and β-keto esters or 1,3-diketones. The catalyst was characterized by usual analytical and spectroscopic techniques. Graphical Abstract
