activators. 3 Very re- cently Wang et al., reported an elegant synthesis of 2-phe- nylquinazolines employing molecular iodine/TBHP and also with supported copper oxide nanoparticles. 4 Truong et al. described copper-catalyzed Ullmann N-arylation coupling process to synthesize 2-phenylquinazolines from the corresponding o-iodobenzaldehydes and benzamidine hydrochloride under ligand-free conditions. 5 However
A novel and efficient protocol for the synthesis of 2-phenyl quinazolinederivatives is developed by recyclable graphite oxide as a catalyst, devoid of moisture sensitive metal catalysts and corrosive acidic reagents. This new procedure has afforded the desired products in good to excellent yields. The graphite oxide can be synthesized by a simple adoptable procedure from inexpensive and readily available
