General description

N,N′-Bis(salicylidene)ethylenediamine (salen) reacts with ferric chloride in acetone solution to yield the complex (Fe salen Cl).

Application

N,N′-Bis(salicylidene)ethylenediamine (salen) immobilized on surfactant-coated alumina has been used as complexing agent for on-line preconcentration of copper and lead by flow injection-flame atomic absorption spectrometry (FI-AAS).

Due to the lack of availability of unnatural (+)-quinic acid as a starting material, a 6-step synthesis of butane diacetal-protected (4S,5S)-dihydroxycyclohexen-1-one (formally derived from (+)-quinic acid) has been devised. The key catalytic asymmetric step involves a chiral Co-salen-catalysed epoxide ring-opening

We have reported the synthesis of a novel salen ligand and its mononuclear Pd-salen complexes derived from 2-{[2-hydroxy-3-{[(E)-(2-hydroxyphenyl)methylidene]amino}propyl)imino]methyl}phenol. The newly synthesized and isolated Pd(II) complexes have been identified and fully characterized by various physico-chemical studies viz., elemental analyses, IR, UV-Vis
