Solvent-free synthesis of polyhydroquinoline derivatives employing mesoporous vanadium ion doped titania nanoparticles as a robust heterogeneous catalyst via the Hantzsch reaction

Mesoporous vanadium ion doped titania nanoparticles were used as reusable catalyst for the synthesis of PHQ derivatives via Hantzsch reaction at 80 °C under greener conditions. The catalyst could easily be recycled and reused without decrease in catalytic activity.
