Fabrication of immobilized molybdenum complex on functionalized graphene oxide as a novel catalyst for the synthesis of benzothiazoles

Abstract

This paper presented a novel amino-modified nano-graphene oxide supported thiophene-2-carbaldehyde Mo-complex (Mo(TC)/GO) catalyst prepared and characterized by FT-IR, SEM, TEM, TGA, EDX, BET, XRD, and N2 adsorption–desorption techniques. The catalyst presented an outstanding performance for synthesizing benzothiazole derivatives through a reaction between benzyl alcohol derivatives and 2-aminothiophenol. The heterogeneous catalyst could be facial separated and reused by filtration without any substantial decline in its catalytic activity even after five runs.
