Excellent yields (85-100%), short reaction time (<60 min.), mild condition, simple work-up, and using a cheap and environmentally friendly catalyst bearing remarkable reusability are advantages of the present methodology. The catalytic efficacy of H5PW10V2O40/MCM-48 over some reported protocols are also overviewed. Graphical Abstract A highly efficient heterogeneous catalytic system is introduced for the high yield (85-100%) preparation of aryl-14-H-dibenzo[a,j]xanthenes by the mediation of H5PW10V2O40 supported on MICM-48 under solvent-free conditions.
