Aquation of Fe–N bonds in pentacyano(ligand)ferrate(2—) ions: electronic and medium effects

Abstract

The rate of Fe–N bond breakage in [Fe(CN)₅L]^n–(L = aromatic amine) ions has been determined for several neutral, anionic, and cationic amines. The results, together with previously reported values for related systems, are used to discuss the mechanism of substitution on [Fe(CN)₅L]^n– systems. The contributions of inner (electronic and electrostatic) and solvent effects to the activation process are discussed.
