Immobilization of a molybdenum complex with tetradentate ligand on mesoporous material MCM-41 as catalyst for epoxidation of olefins
Covalent grafting of MCM-41 with 3-chloropropyl trimethoxysilane and subsequent reaction respectively with acacdien and complexation with MoO2(acac)2 afforded MoO2acacdien@MCM-41. X-ray diffraction and nitrogen sorption analyses revealed the preservation of the textural properties of the support as well as accessibility of the channel system despite sequential reduction in surface area, pore vo...
متن کاملNickel(II) and Copper(II) Complexes of a New Tetradentate Schiff Base Ligand: Synthesis, Characterization, Thermal Studies and Use as Precursors for Preparation of NiO and CuO Nanoparticles
A new tetradentate N2O2 Schiff base ligand (MeO-bph)2bn = N,N¢-bis(2-hydroxy-4-methoxybenzophenone)-1,4-butanediamine was prepared from the condensation of butane-1,4-diamine with 4-methoxy-2-hydroxybenzophenone and characterized by 1H-NMR spectroscopy and single-crystal X-ray diffraction. Its nickel(II) and copper(II) complexes characterized usin...
متن کاملThe Necessity of Having a Tetradentate Ligand to Extract Copper(II) Ions from Amyloids
The accumulation of redox-active metal ions, in particular copper, in amyloid plaques is considered to the cause of the intensive oxidation damage to the brain of patients with Alzheimers disease (AD). Drug candidates based on a bis(8-aminoquinoline) tetradentate ligand are able to efficiently extract Cu(2+) from copper-loaded amyloids (Cu-Aβ). Contrarily, in the presence of a bidentate hydroxy...
متن کاملStudy the Interaction of Ni Complex of Tetradentate Schiff Base Ligand with HEN Egg White Lysozyme
AbstractInteraction of Ni complex(Salen= N, N´-ethylene bis(salicylideneimine)) with hen egg-white lysozyme (HEWL) was studied by absorption spectroscopy, competitive binding study and thermal denaturation study. The protein binding affinity of Ni complex was found to be (3.0×103M−1). The binding plot obtained from the absorption titration data gives a binding constant of 2.4 (± 0.3)×103 M...
متن کاملKinetics and mechanism of ligand exchange reaction of copper(II) complexes with tetradentate Schiff base ligands.
The kinetics of a ligand exchange in the CuL4/H2Ln system, where H2Ln is the N,N'-alkylen-bis(salicyldimine) tetradentate Schiff base ligand (n = 2 or 3, CH2 groups in the chain length of the amine backbone) was studied spectrophotometrically in DMF solvent with or without triethylamine (NEt3) and H2O at 25 ± 0.1 °C and an ionic strength of 0.01 M NaNO3. The reaction rate was found to be first-...
