Several 2,5-dimethyl-N-substituted pyrroles were prepared by the condensation of different substituted anilines with 2,5- hexanedione using nano lead oxide as an efficient and recyclable catalyst.All the synthesized compounds are confirmed through IR, ~1H NMR,~(13)C NMR and mass spectral data.Nano lead oxide β-PbO(P85) was prepared by dissolving lead acetate dihydrate in 1- propanol at a pH 9.0 under stirring at 85℃.The structural study and surface morphology of the lead oxide(PbO) were characterized using X-ray diffraction(XRD),Scanning electron microscopy(SEM) and the functional groups of the PbO sample were investigated using infrared spectrophotometer.
