    Synthesis, characterization and catalytic activity of Nano-Iron (II) schiff base complex in Suzuki-Miyaura cross coupling reaction
    (Science Publishing Corporation Inc ijet@sciencepubco.com, 2018) Ansari, R.M.; Badekai Ramachandra, B.R.
    A new nano-iron (II) Schiff base complex, [Fe(L)] where L is 1-((pyridin-2-ylimino)methyl)naphthalen-2-ol with octahedral geometry has been synthesized by the sonochemical (Ultrasonic irradiation) method. This method can promote the formation of nano-sized particles in short time with improved yield toward conventional method. The complex was characterized by FTIR, UV-Vis, TGA, SEM and elemental analysis. Particle size of synthesized complex was calculated from particle size analysis. Catalytic activity of the prepared complex was studied for Suzuki-Miyaura cross-coupling reaction. The synthesized complex showed great potential in catalytic activity with less concentration. © 2018 Authors.

    Copper (II) Schiff base-graphene oxide composite as an efficient catalyst for Suzuki-Miyaura reaction
    (Elsevier B.V., 2019) Ansari, R.M.; Badekai Ramachandra, B.R.
    Transition metal copper (II) Schiff base composite (Cu–NH2–GO) was synthesized using functionalized graphene oxide with (3-aminopropyl) methoxysilane (APTMS). X-ray diffraction, FTIR spectroscopy and thermogravimetric analyses ascertained the incorporation of the copper (II) Schiff base on the functionalized graphene oxide. Scanning electron microscopy and TEM evidences further confirmed the surface morphology of the composite. Catalytic activity study indicated that the synthesized Cu–NH2–GO was active for cross-coupling of aryl halide with phenylboronic acid. Above 84% (4-Iodobenzonitrile) biphenyl conversion could be achieved using Cu–NH2–GO catalyst in the C–C coupling reaction. © 2018 Elsevier B.V.
