Abstract

This is the first report of supporting zinc cation on ƛ‐carrageenan/Fe3O4 magnetic
nanoparticles. The structural and magnetic properties of this hybrid (Zn2+/ƛ‐carrageenan/
Fe3O4 nanoparticles) were identified using various techniques. This green
and efficient catalytic system was applied in the synthesis of biologically important
quinolines. The products were obtained in good to high yields (52–95%) from a
one‐pot reaction procedure involving aromatic aldehydes, enolizable aldehydes
and aniline derivatives. Our method has many advantages such as mild reaction
conditions, easy work‐up, use of a reusable magnetic catalyst and high yields of
products.
