چکیده مقاله :
Anchored sulfonic acid on the surface of a silica-coated cobalt ferrite core was efficiently applied in the one-pot preparation of 1-amidoalkyl-2-naphthols under solvent-free conditions at 80 oC. The catalyst is readily recovered by simple magnetic decantation and can be recycled 10 times with no significant loss of catalytic activity.
