A novel magnetic nanoparticles is prepared and characterized, then its catalytic application is investigated in the synthesis of tetrahydrobenzo[b]pyrans. The Fe۳O۴@ SiO۲@/Pr- N=Mo[Mo۵O۱۸]nanocatalyst was characterized by Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). This magnetic nanocatalyst exhibited high activity in the synthesis of tetrahydrobenzo[b]pyrans and gave corresponding products in high yield.
