Abstract

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(3H)-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. © 2019 John Wiley & Sons, Ltd.
