| Abstract: | A series of Cu(II) complexes of Schiff bases
derived from
the condensation of o-aminothiophenol
with 2-hydroxy-
1-naphthaldehyde or salicylaldehyde or its derivatives (Br, Cl, NO2 or
CH3) have been reported. The structural features of the complexes have
been obtained from their elemental analyses, magnetic susceptibility, IR,
electronic and EPR spectral studies. IR spectra suggest that these ligands act
as tridentate dibasic donor coordinating through the phenolic oxygen,
azomethine nitrogen and thiophenol sulphur atoms. Magnetic moments, electronic
spectra and EPR spectra of the complexes suggested a square planar geometry
around the Cu(II) ion. The redox behaviour of copper complexes has been studied
by cyclic voltammetry. The new Cu(II) complexes have been utilized as catalysts
for N-arylation of imidazole. |
