Aluminatesulfonic acid nanoparticles (ASA-NP) as catalyst were prepared and extensively identified using TEM, TGA, XRD, EDAX, and FT-IR. These analytical techniques provided comprehensive insights into the morphological, thermal, structural, elemental, and functional properties of the synthesized nanoparticles. Subsequently, xanthene derivatives were efficiently synthesized via a one-pot reaction involving 2-naphthol or cyclic diketones and aldehydes. The reaction was prompted by ASA under solvent-free conditions, employing conventional thermal activation. This methodology presents some significant advantages such as operational simplicity, environmentally favorable reaction, accelerated reaction kinetics, and excellent product yields. Furthermore, the post-reaction purification process is straightforward, minimizing complexities associated with product isolation. Notably, the catalyst demonstrates exceptional recyclability, retaining its catalytic activity across multiple reaction cycles without substantial deactivation, highlighting its robustness and sustainability for future applications.
