Functionalized Nano Graphene Platelets as Green Catalyst to Synthesize New and Known Benzoyl-1,4-diazanaphthalene and Study of Their Local Aromaticity

<p>Functionalized graphene has been prepared and employed for the solvent-free synthesis of some novel and known benzoyl-1,4-diazanaphthalene from the condensation of various arylglyoxals with 4-bezoyl-1,2-phenylenediamine. Catalyst loads as low as 0.003 g could be used leading to high yields of pure products. Magnetic, geometry, and electronically based indices have been also employed to investigate the correlation between aromaticity variation in new formed ring (ring A) and yield of reaction.</p>
