Experimental study demonstrates efficient quinazolinone synthesis using a reusable magnetic palladium catalyst, highlighting a practical carbon monoxide-alternative pathway.
In this paper, a novel catalyst is introduced based on the immobilization of palladium on modified magnetic graphene oxide nanoparticles. The catalyst is characterized by several methods, including transmission electron microscopy, scanning electron microscopy, X‐ray fluorescence, vibrating‐sample magnetometer, Fourier transform‐infrared and dynamic light scattering (DLS) analysis. The activity of the catalyst was investigated in the synthesis of 4(3 H )‐quinazolinones via Pd‐catalyzed carbonylation‐cyclization of N ‐(2‐bromoaryl) benzimidamides by Mo (CO) 6 . The Mo (CO) 6 is used as a carbon monoxide source for performing the reaction under mild conditions. The catalyst showed good reusability, and no change in activity was observed after 10 cycles of recovery.
