Hexatungstate -supported functionalized graphene oxide efficient protocol for the synthesis of benzothiazoles

Abstract A new amino-modified graphene oxide supported Lindqvist-type polyoxometalate([n-Bu4N]2[W6O19]) catalyst was prepared and identified by FT-IR, TGA, SEM, XRD, EDX, and Raman techniques. So, the new catalyst(W6O18@GO) performance of this recyclable catalyst was determined to promote the synthesis of benzothiazole derivatives at 60 °C under reaction conditions. heterogeneous catalyst of (W6O18@GO) is easily separated and successfully reused up at least 5 times with a slight loss of yield of the desired product.
