Title
Magnetic CoFe2O4 nanoparticle immobilized N-propyl diethylenetriamine sulfamic acid as an efficient and recyclable catalyst for the synthesis of amides via the Ritter reaction
Abstract

•CoFe2O4 nanoparticle immobilized diamine-N-sulfamic acid was prepared.•Excellent activity for the synthesis of amides via the Ritter reaction was observed.•The catalyst could be easily recovered by magnetic separation.•The catalyst was reused several times without significant loss of activity.

A magnetic CoFe2O4 nanoparticle immobilized diamine-N-sulfamic acid (CoFe2O4@SiO2–DASA) was synthesized and used as efficient heterogeneous catalyst for the synthesis of amides via the Ritter reaction under solvent-free conditions. The magnetic nanocatalyst could be readily recovered by applying an external magnet and recycled several times without considerable loss of its catalytic activity.
