1,4-Butane-Sultone Functionalized Graphitic Carbon Nitride as a Highly Efficient Heterogeneous Catalyst for the Synthesis of 2,3-Dihydroquinazolines Derivatives

Abstract

1,4-Butane-sultone functionalized graphitic carbon nitride nanosheets (g-C3N4@Bu-SO3H) was prepared and applied as an efficient heterogeneous catalyst for the synthesis of various quinazolines derivatives with high yield. In next step, the structure and morphology of catalyst was characterized by different analyses such as, FT-IR, EDS, XRD and FE-SEM. On the other side, considering the noticeable features of g-C3N4@Bu- SO3H such as high stability, easy to synthesize, non-toxicity, excellent reusability, and so on, the synthesis of 2,3-dihydroquinazolines derivatives with numerous advantages such as short reaction time reaction condition, easy separation and etc were realized.
