coumarins are formed via Pechmann condensation using various substituted phenols and ethyl acetoacetates in the presence of xanthansulfuricacid as a solidacidcatalyst under solvent-free conditions. This method is very simple, cost-effective, and has shorter reaction times, and the catalyst could be reused. GRAPHICAL ABSTRACT
