The development of bimetallic iron oxide-silver magnetic nanoparticles (Fe2O3-Ag MNPs) catalytic system provides an efficient heterogeneous synthetic pathway to allylic amines and 1,2-dihydroquinolines involving the direct inter/intramolecular nucleophilic substitution of pi-activated alcohols with electron-deficient amines. The major advantages of the present method are wide substrate scope, simple product separation, low catalyst loading, and magnetically recyclable catalyst. (C) 2015 Elsevier Ltd. All rights reserved.
