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
