abstract

nanomagnetite-fe3o4 is used as a highly efficient, mild, green and recyclable nanomagnetite catalyst for the synthesis of 4,4´-(arylmethylene)-bis(3-methyl-1-phenyl-1h-pyrazol-5-ol) derivatives in solvent-free conditions. the condensation reaction of 3-methyl-1-phenyl-1h-pyrazol-5(4h)-one with aromatic aldehydes affords the title compounds in high yields and short reaction times. the nanocatalyst is reusable for seven times without significant loss of its catalytic activity. short reaction times, high yields, generality, efficiency, recyclability of the catalyst for seven times, simple purification, clean reaction, and agreement with the green chemistry protocols are some advantages of in this method. the catalyst was characterized by transmission electron microscopy (tem), fourier transform infrared spectroscopy (ft-ir), x-ray diffractometer (xrd) and vibrating sample magnetometer (vsm).

Application of ZrO2–SO3H as highly efficient recyclable nano-catalyst for the green synthesis of fluoroquinolones as potential antibacterial

Various antibacterial fluoroquinolone compounds were prepared by the direct amination of 7-halo-6- fluoroquinolone-3-carboxylic acids with variety of piperazine derivatives and (4aR,7aR)-octahydro-1H-pyrrolo[3,4-b] pyridine using Zirconia Sulfuric Acid (ZrSA) nanoparticle, as a catalyst in refluxing water. The results showed that ZrSA exhibited high catalytic activity towards the synthesis of f...
