Catalytic potential of new mononuclear Cr(III)-Schiff base complexes for selective oxidation of benzyl alcohol by H2O2
IN THE PRESENT CONTRIBUTION, SOME NOVEL CR(III) COMPLEXES WERE SYNTHESIZED FROM TRI- AND TETRA-DENTATE IMINE LIGANDS DERIVED FROM 3-ETHOXYSALICYLALDEHYDE OR 2-HYDROXYNAPHTHALDEHYDE WITH 2-AMINOPHENOL OR _O_-PHENYLENEDIAMINE. ALL THE PREPARED LIGANDS WERE AUTHENTICATED BY IR, 1H, 13C NMR SPECTRA AND CHN ANALYSIS. INTERACTION OF THE SYNTHESIZED LIGANDS WITH CHROMIUM NITRATE PRODUCED THREE NOVEL CR(III) COMPLEXES. THE STRUCTURE OF THE PREPARED CR(III) COMPLEXES ... Read more

Synthesis, catalysis, antimicrobial activity and DNA interactions of new Cu(II)-Schiff base complexes
Structural features and catalytic activities of five ternary copper (II)-Schiff base complexes are investigated. The ligands are derived from 3–methoxysalicylaldehyde (MS) or 4– diethylaminosalicylaldehyde (DS) and amino acids {L-phenylalanine (Phe), L histidine (His) or DL-tryptophan (Trp)}, as primary ligands, and 2,4’-bipyridyl (DP) as secondary ligand. Cu(II)- complexes are characterized by various physicochemical tools. The catalytic efficiency of Cu(II)-complexes is studied ... Read more
