PVA/Fe(NO3)3 nanofiber mats: an efficient, heterogeneous and recyclable catalyst for the synthesis of quinolines via Friedländer annulations

Abstract

PVA/Fe(NO₃)₃ nanofiber mats are found to be a heterogeneous recyclable catalyst for the efficient synthesis of quinoline derivatives in the Friedländer condensation of 2-aminoarylketones with carbonyl compounds and β-keto esters. The novel catalytic system could be recovered and reused at least 5 times without any loss of catalytic activity.
