Poly (N-2-aminoethylacrylamide) grafted polystyrene–Cu (II) complex catalyzed conversion of aldehydes into primary amides in water

• Polyacrylamide-g-PS functionalized with ethylene diamine is complexed with Cu+ 2.
• Catalyst shows good activity for the conversion of aldehydes to amides in water.
• The catalyst exhibited significant recyclability for five consecutive recycles.

Poly (N-2-aminoethylacrylamide) grafted polystyrene–Cu (II) complex was synthesized and characterized by techniques such as FTIR spectroscopy, XRD, SEM–EDX, TGA and ICP-AES analysis. The catalyst exhibits an excellent catalytic activity for the conversion of various aldehydes to corresponding amides in water. Also, the catalyst could be recovered and reused five times without any significant loss in its activity.
