Kurapati, Sathish Kumar published the artcilecis-Dioxomolybdenum(VI) complexes with unsymmetric linear tetradentate ligands: syntheses, structures and bromoperoxidase activities, SDS of cas: 92093-23-7, the main research area is dioxomolybdenum hydroxyethylamino substituted phenol complex preparation electrochem; aralkyl bromide preparation dioxomolybdenum hydroxyethylamino substituted phenol catalyst; oxidative bromination dioxomolybdenum hydroxyethylamino substituted phenol catalyst; crystal structure dioxomolybdenum hydroxyethylamino ethylamino methyl substituted phenol complex.
Reactions of [MoO2(acetylacetonate)2], 2-((2-(2-hydroxyethylamino)ethylamino)methyl)-4-R-phenols (H2Ln, n = 1 – 5 for R = H, Me, OMe, Cl and Br, resp.) and KOH in 1:1:2 mol ratio in methanol afford a series of complexes having the general formula cis-[MoO2(Ln)] (1-5) in 81-86% yields. The complexes have been characterized using elemental anal., spectroscopy (IR, UV-visible, and 1H NMR, 13C NMR and 13C-DEPT NMR) and electrochem. measurements. The mol. structures of 1-4 have been determined using single-crystal x-ray crystallog. In each of 1-4, the ONNO-donor 6,5,5-membered fused chelate rings forming (Ln)2- and the two mutually cis oxo groups assemble a distorted octahedral N2O4 coordination sphere around the metal center. In the crystal lattice, each of 1-4 forms a one-dimensional infinite chain structure via intermol. N-H···O hydrogen bonding interactions. In cyclic voltammograms, the diamagnetic complexes display an irreversible metal-centered reduction in the potential range -0.73 to -0.88 V (vs. Ag/AgCl). The physicochem. data are consistent with a very similar gross mol. structure for all of 1-5. All the complexes exhibit decent bromoperoxidase activities and are also able to effectively catalyze benzoin and methyl(phenyl)sulfide oxidation reactions.
