A mild, efficient and environmentally benign method is adopted in the synthesis of aryl
bis(heterocyclyl)methanes in water over mesoporous zirconium phosphate. The catalyst has been prepared
following surfactant templated EISA (Evaporation Induced Self Assembly) method. The catalytic
applications of mesoporous zirconium phosphate have been limited in organic multicomponent synthesis.
It involves the condensation of various aromatic aldehydes with different active heterocycles
like 4-hydroxycoumarin, pyrazolones and indole affording the corresponding product in high yield
within a short time. The catalyst was reused several times without much change in the activity.
Keywords: Green synthesis, Bis(heterocyclyl)methanes, zirconium phosphate, mesoporous, aqueous medium, reusable.
