New mixed-ligand 8-hydroxyquinolinato iron(III) complexes of dimethylethylenediamine-based aminophenol ligands

Four new mixed ligand iron(III) complexes of N,N′-dimethylethylenediamine based bis(phenol) di-amine (H2LNER) and 8-hydroxyquinoline (HQ) ligands have been synthesized and characterized by spectroscopic methods, X-ray diffraction, ma

TEMPO-mediated aerobic oxidation of alcohols using copper(II) complex of bis(phenol) di-amine ligand as biomimetic model for Galactose oxidase enzyme

Mononuclear copper complexes of four-dentate N2O2 bis(phenol) diamine ligands (H2LNEX X: C and OB in which C and OB are chloro and tert-butyl-methoxy substituents on phenol groups) have been synthesized and characterized by IR, UV-Vis, single crystal X-ray diffraction, magnetic susceptibility studies and cyclic voltammetry techniques. The CuLNEX complexes show the square pyramid geometry of the coordination sphere with the copper centers surrounded by two nitrogen and oxygen atoms from the coordinating ligand and an axially bound water molecule. The effective magnetic moments of 1.7 and 1.8 BM confirm a monomer complex with copper(II) center. Electrochemical oxidation of these complexes yielded the corresponding Cu(II)-phenoxyl radical species. In addition, CuLNEX complexes, have shown efficient catalytic activities for TEMPO-mediated oxidation of a set of alcohols to the corresponding aldehydes in the presence of molecular oxygen as oxidant at room temperature.

Iron(III) complexes of ethylenediamine derivatives of aminophenol ligands as models for enzyme-substrate adducts of catechol dioxygenases

In the present work, six N,N'-dimethylethylenediamine derivatives of substituted aminophenol ligands (H2LNEX, X: C, B, M, BM, Bu and OB) were synthesized by a convenient, green procedure. The mentioned ligands were characterized by 1

Structure and dynamics in solution of bis(phenoxy-amine)zirconium catalysts for olefin polymerization

The activity of two bis(phenoxy-amine)ZrR2 precatalysts (bis(phenoxy-amine) = N,N'-(3-tBu-5-OMe-2-C6H 2OCH2)2-N,N'-Me2-(NCH 2CH2N); R = Me (1), Bn (2, benzyl)) toward propene polymerization has been evaluated using different activators and cocatalysts: MAO, MAO/TBP, B(C6F5)3/TIBA, and [CPh 3][B(C6F5)4]/TIBA (MAO = methylalumoxane, TBP = 2,6-di-tert-butylphenol, TIBA = triisobutylaluminum). It was found that the nature of the activator affects the activity only to a small extent. NMR studies in solution and DFT calculations on the 3a-c and 4a-c(a, MeB(C6F5)3-; b, BnB(C 6F5)3-; c, B(C6F 5)4-) ion pairs deriving from the activation processes of 1 and 2, respectively, showed that three isomers can form. All of them have the anion in the second coordination sphere, whereas the binding modality of the ligand leads to the mer-mer most stable isomer, fac-mer isomer of intermediate stability, and fac-fac least stable isomer. Notably, the energy of the fac-fac isomer, which is supposed to be the active species in the polymerization process, depends more on the R group and not much on X-, in agreement with the small influence of the activators on the polymerization activity.
