Niobium tetrahalide complexes with neutral diphosphine ligands.
The reactions of NbCl4 with diphosphine ligands o-C6H4(PMe2)2, Me2PCH2CH2PMe2 or Et2PCH2CH2PEt2 in a 1 : 2 molar ratio in MeCN solution produced eight-coordinate [NbCl4(diphosphine)2]. [NbBr4(diphosphine)2] (diphosphine = o-C6H4(PMe2)2 or Me2PCH2CH2PMe2) were made similarly from NbBr4. X-ray crystal structures show that [NbCl4{o-C6H4(PMe2)2}2] has a dodecahedral geometry, but the complexes with...
متن کاملVibrational circular dichroism spectroscopy of two chiral binaphthyl diphosphine ligands and their palladium complexes in solution.
BINAP (2,2'-diphenylphosphino-1,1'-binaphthyl) is a unique binaphthyl diphosphine ligand with axial chirality. The palladium complexes of BINAP and of its derivative TOLBINAP have found extensive applications in the field of asymmetric syntheses. The conformational changes in the BINAP and TOLBINAP ligands before and after coordination with palladium have been investigated using density functio...
متن کاملAsymmetric hydrogenation of quinazolinium salts catalysed by halide-bridged dinuclear iridium complexes bearing chiral diphosphine ligands.
Asymmetric hydrogenation of quinazolinium salts was catalysed by halogen-bridged dinuclear iridium complexes bearing chiral diphosphine ligands, yielding tetrahydroquinazoline and 3,4-dihydroquinazoline with high enantioselectivity. A derivative of chiral dihydroquinazoline was used as a chiral NHC ligand.
متن کاملTheoretical Study of effect ligands on Molecular & Orbital Properties of Cu complexes of industrial dyes formazan
In this research at the first complexes were optimized. NBO calculations and NMR for the complexes were carried out at the B3LYP/6-31G*quantum chemistry level. Different parameters such as energy levels, the amount of Chemical Shift in different atoms, the amount of HOMO/LUMO, chemical potential (µ ), chemical hardness (η), Formazan dyes have become important reactive dyes for cotton. Formazan ...
متن کاملDinuclear planar chiral ferrocenyl gold(I) & gold(II) complexes.
Oxidation of Au(I) in the presence of Fe(II) allowed for the synthesis of unique dinuclear ferrocenyl Au(II) complexes via the first reported enantiopure planar chiral ferrocenyl Au(I) complex. (Spectro)electrochemical studies show that oxidation at Fe(II) is favoured, but DFT studies suggest that the energy differences for oxidation of one or the other metal should be quite small.
