Fe3O4@Sucrose: A Green Catalyst for Syntheses of Polyhydroquinolines.

Abstract

By aid of environmental-friendly, moderated conditions and a novel hydrogen-bond-rich Nano catalyst, we ran a simple synthesis of penta-substituted Polyhydroquinolines (PHQs). Expected products have been made from two different sorts of 1,3-dicarbonyls, conjugated aldehydes and ammonium acetate. New core-shell type, magnetic nanoparticles (MNPs) after formation based on table sugar as an inexpensive carbohydrate are precisely characterized using common analyses such as FT-IR, XRD, VSM, TGA, SEM and EDX. Besides its economical or semi-industrial purposes, reusability of magnetic catalyst developed its great interest in replacement of conventional homogeneous promoters. This property has led to total yield for more than 78% of starting performance (after 7 th run) is considerable.
