Item Synthesis, characterization and catalytic activity of Fe(III) complexes containing Schiff base and triphenylphosphine ligands(2010) Rani, S.; Badekai Ramachandra, B.The oxidation of alcohols to carbonyls was investigated by an efficient catalyst system comprising of Fe(III)-Schiff base-triphenylphosphine complex. The complex chloroN-(2-mercaptophenyl)salicylideneiminebis(triphenylphosphine) iron(III) showed higher activity for oxidation of various alcohols under relatively mild conditions. © 2010 Elsevier B.V.

All rights reserved.Item Transition metal complexes of 5-bromosalicylidene-4-amino-3-mercapto-1,2,4- triazine-5-one: Synthesis, characterization, catalytic and antibacterial studies(Serbian Chemical Society, 2011) Ramasubramanian, A.S.; Badekai Ramachandra, B.; Dileep, R.; Rani, S.Transition metal complexes of 5-bromosalicylidene-4-amino-3-mercapto-1,2,4- triazine-5-one with metal precursors, such as Cu(II), Ni(II), Co(II) and Pd(II), were synthesized and characterized by physico-chemical and spectroscopic techniques. All the complexes are of the ML type. Based on analytical, spectral data and magnetic moments, the Co(II) and Ni(II) complexes were assigned octahedral geometries, while the Cu (II) and Pd(II) complexes square planar. A study on the catalytic oxidation of benzyl alcohol, cyclohexanol, cinnamyl alcohol, 2-propanol and 2-methyl-1-propanol was performed with N-methylmorpholine-N-oxide (NMO) as co-oxidant. All the complexes and their parent organic moiety were screened for their biological activity on several pathogenic bacteria and were found to possess appreciable bactericidal properties. © 2011 Copyright (CC) SCS.
