Abstract A one-pot synthesis of functionalized benzofurans has been developed via O-alkylation, carbon–carbon coupling/cyclization, and dehydration/olefination tandem reactions from phenacyl bromide and phenols undermicrowaveirradiation and solvent-freeconditions in the presence of mineral-supported reagent and inorganic base. The best selectivity for forming benzofuran product has been achieved
