Catalytic evaluation of newly prepared GO-SB-H2PMo as an efficient and reusable nanocatalyst for the neat synthesis of amidoalkyl naphthols

Abstract

The catalytic activity of newly prepared functionalized graphene oxide nanosheets, denoted as GO-SB-H2PMo, has been investigated in the synthesis of amidoalkyl naphthols through the one-pot, three-component reaction of β‐naphthol with various aryl aldehydes and acetamide. The reactions occur under solvent-free conditions and the process is operative with various aryl aldehydes, giving the corresponding products in high yields over short reaction times. Moreover, the catalyst could be easily recovered from the reaction mixture and reused such that considerable catalytic activity can still be achieved after the fifth run.
