benzaldehyde, and acetamide. A series of amidoalkyl naphthols were obtained
under thermal, solvent-free conditions. We demonstrated a green procedure which
offers advantages, such as simple work-up, shorter reaction times, excellent yields,
environmentally benign, reusability of catalyst, and cost-effective recovery. The
repeated use of the catalyst shows that the catalyst was highly active after
successive five runs. Consequently, this one-pot synthesis offers the synthetic utility
of the lead sulfide nanoparticles as versatile reagents in organic chemistry.
