Copper-diamsar Functionalized SBA-15 as a Novel Nanocatalyst for the Synthesis of Benzothiazole derivatives in water media

Cu(II)-diamsar complex functionalized mesoporous SBA-15 silica supports was employed for the synthesisof benzothiazole heterocycles in water media as a green solvent with excellent yields. The resulted catalyst isextraordinarily stable and inhibits leaching of the metal ion from the SBA-15 support. Furthermore, it showed goodheterogeneous catalytic activity in the synthesis of aforementioned heterocycles and also could be recycled from thereaction mixture and used again for 6 times. The nature of the support after the grafting of Cu(II)-diamsar complex onthe surface of SBA-15 nanochannels and successful grafting was examined by X-ray diffraction (XRD), transmissionelectron microscopy (TEM).
