Summary Kinetics of nucleophilic substitution at a range of low-spin iron(II)diimine complexes have been examined in the presence of a variety of salts, to probe the role of hydroxide and cyanide as nucleophiles and of other ions in ion association equilibria. Equilibrium constants for interaction of hydroxide and of cyanide with many of these ligands, free or complexed with iron(II) or molybdenum(0), have been measured, in water and in binary aqueous solvent mixtures. Effects of solvent, temperature, and pressure on rate constants and on equilibrium constants have been monitored for selected systems. In the light of these results, and of ancillary qualitative observations, we discuss the role and nature of intermediates in nucleophilic substitution reactions of transition metaldiimine complexes.
