Syntheses, Characterization and Solvatochromism Study of Heteroleptic Chelated Copper(II) Complexes Containing N,N- dibezyl Substituted Ethylenediamine and Acetylacetonate Ligands
A series of new heteroleptic chelated copper(II) complexes that encompass N,N-dibezyl substituted derivative of ethylenediamine (X-diamine) and acetylacetonate (acac) were prepared. The IR and electronic absorption spectra and the molar conductivity of the complexes are presented and discussed. The molar conductivity values of the complexes in different solvents reveals a predominance of elec...
متن کاملSyntheses, crystal structures and magnetic properties of three novel cobalt(II) complexes containing imidazole derivative groups.
Three Co(II) complexes with the formulas: {[Co2(Bib)3Cl2]Cl(CH3COO)}.CH3OH.H2O (1), [Co2(Bib)3Cl2]Cl2.(CH3OH)2.H2O, (2) and [Co3K1(Tib)2(CH3COO)6]PF6 (3), were obtained by self-assembly of a cobalt(II) salt with Bib and Tib (Bib = 1,3-bis(4,5-dihydro-1H-imidazol-2-yl)benzene; Tib = 1,3,5-tris(4,5-dihydro-1H-imidazol-2-yl)benzene) and were structurally and magnetically characterized. X-Ray singl...
متن کاملProbing the capabilities of copper complexes with nitrogen and sulfur containing macrocyclic ligands as aziridination catalysts
Aziridines are three:membered rings containing one nitrogen atom. They are useful as synthetic intermediates in many organic reactions. Much work has been devoted to synthesizing their analogs, cyclopropanes and epoxides, but little work has been done on the aziridination reaction. This study endeavored to probe the efficiencies of novel copper aziridination catalysts with N3 and 53 macrocyclic...
متن کاملStructurally diverse copper(II) complexes of polyaza ligands containing 1,2,3-triazoles: site selectivity and magnetic properties.
Copper(II) acetate mediated coupling reactions between 2,6-bis(azidomethyl)pyridine or 2-picolylazide and two terminal alkynes afford 1,2,3-triazolyl-containing ligands L(1)-L(6). These ligands contain various nitrogen-based Lewis basic sites including two different pyridyls, two nitrogen atoms on a 1,2,3-triazolyl ring, and the azido group. A rich structural diversity, which includes mononucle...
