Reaction of 1-benzoylethylpyridinium-4-aldoxime chloride with aquapentacyanoferrate(II)

The kinetics and mechanism of the substitution reactions of the aquapentacyanoruthenate(II) ion with naphthalene‐substituted ligands in aqueous medium

“…The enhanced interest in the low-spin aquapentacyanoruthenate(II) ion, i.e., [Ru(CN) 5 H 2 O] 3− , lies in the fact that it represent models for biological systems and has been used for investigation of specific binding groups in amino acids [15] and peptides. It can also coordinate typically with only one additional incoming or substituting ligand, easily losing a coordinated water molecule and subsequently forming highly stable nitrogen heterocyclic substituted complexes.…”

“…The rates of substitution for the low-spin [Ru(CN) 5 3− ion with two naphthalenesubstituted ligands, viz. nitroso-R-salt and α-nitroso-β-naphthol (further designated as NRS and αNβN, respectively, throughout the text), and the results are compared with previously reported systems on Ru(II) [13].…”

“…The progress of the reaction was subsequently followed by monitoring the increase in absorbance at 525 nm in both the cases where the product, [Ru(CN) 5 …”

“…During the past two decades, a variety of complexes substituted with N, O, S, and P donor atoms have been synthesized from labile, [Fe(CN) 5 3− . In recent years, much attention has been paid toward the studies concerning the ligand substitution reactions of low-spin pentacyano(ligand)ferrate(II) complexes with a variety of ligands in aqueous medium [4,5], miceller medium [6][7][8], as well as in electrolyte media [9,10] by many investigators.…”
