Synthesis, characterization and applications of metal complexes of 5-nitrosalicylidene 4-amino 3-mercapto-1, 2, 4-triazine- 5-one
(2010) Ramasubramanian, A.S.; Badekai Ramachandra, B.; Ramakrishna, R.
Transition metal complexes of Cu(II), Ni(II), Co(II) with 5- Nitro salicylidene 4- amino 3 -mercapto 1,2,4 triazine-5-one have been synthesized and characterized by analytical and spectral techniques. All metal complexes form ML type of complexes. Based on analytical data, IR spectra and magnetic moments Co (II), Ni (II) are assigned octahedral geometries while Cu (II) a square planar geometry. In all these complexes azomethine nitrogen, carbonyl oxygen and phenolic oxygen are involved in bond formation.
Cobalt complexes in [EMIM]Cl - A catalyst for oxidation of alcohols to carbonyls
(2010) Ramakrishna, R.; Badekai Ramachandra, B.
A coordination complex system consisting of Cobalt (II)-Schiff bases with triphenylphosphine were synthesized and characterized. These catalysts were effective in the oxidation of primary and secondary alcohols. The oxidation reactions were carried out in ethyl-methyl-imidazolium ionic liquid in presence of NaOCl. Higher catalytic activity was observed for CoL1. © 2009 Elsevier B.V. All rights reserved.
