Nine different bis(arylimino)pyridine complexes of Fe(III) with different halide substituents (F, Cl, Br, I) at different positions of the iminophenyl group of the ligand have been synthesized, characterized and applied for homogeneous 1-pentene and 1-hexene oligomerization and co-oligomerization reactions after activation with methylaluminoxane (MAO). The best activity in 1-hexene oligomerizat...
Erratum to “Synthesis, characterization and crystal structure of platinum(II) complexes with thiourea derivative ligands” [Eur. J. Chem. 9 (4) (2018) 360-368].
the oxidation of complexes of ti(iii), (til6)3+ (l=ur, meur, dmeur, deture, n-bu-ur, and phur), by iodine as i3- in ethanol and acetonitrile solutions, appears to proceed as a second order reaction and is much faster in ethanol solution (where solvolysis occurs) than in acetonitrile. the enthalpy of activation appears to decrease as ligand's size increases which suggest that the kinetic stabili...
We introduce and study a class of objects that encompasses Christensen Foxby’s semidualizing modules complexes Kubik’s quasi-dualizing modules: the [Formula: see text]-adic complexes. give examples equivalent characterizations these objects, including characterization in terms more familiar property. As an application, we proof existence dualizing over complete local rings does not use Cohen St...
The synthesis and characterization of mixed ligand complexes of Fe (III) with tartaric acid/succinic acid and heterocyclic amines. These complexes were characterized on the basis of elemental analysis, conductometric, magnetic measurements, UVvis, IR spectral studies. All the complexes were found electrolytic and paramagnetic in nature with high spin octahedral structure. The synthesized comple...
few novel cobalt(ii) and copper(ii) complexes [m(fmp)3]cl2, [m(fmp)(bpy)2]cl2,[m(fmp)(phen)2]cl2 and [m(fmp)(phen)(bpy)]cl2 (fmp = 3-furan-2-ylmethylene-pentane-2,4-dione, phen = 1,10-phenanthroline, bpy = 2,2'-bipyridine) have been synthesized andcharacterized by elemental analyses, molar conductance, magnetic susceptibility measurements,ir, electronic, epr, mass spectra and cyclic voltam...
