Kinetics of substitution at bis(2,2′-bipyridyl)biscyanoiron(II)

Abstract

The kinetics of reaction of Fe(bipy)₂(CN)₂ with 1,10-phenanthroline have been investigated in water and in mixed aqueous solvents. Logarithms of rate constants for this reaction, and for the analogous reaction of a Schiff base complex Fe(SB)₂(CN)₂, where SB =N-(2-pyridylmethylene)-3,4-dimethylaniline, correlate linearly with Grunwald–Winstein solvent Y values. Reaction of Fe(bipy)₂(CN)₂ with hydroxide follows a first-order rate law with rates independent of hydroxide concentration.
