摘要：

Biscoumarin derivatives are synthesized via a simple, one-pot, pseudo three-component reaction between various arylaldehydes and 4-hydroxycoumarin using phospho sulfonic acid as a reaction mediator under solvent-free neat conditions in good to excellent yields. High yields, short reaction time, easy work-up, elimination of solvents and environmentally benign milder reaction conditions are the advantages of this procedure.
