Dark reactivity of [Fe(phtmeimb)2]+ with 4-Br-benzene diazonium. Absorption changes (left) recorded in acetonitrile at selected time intervals for a solution of [Fe(phtmeimb)2]+ (230 μM) in the presence of 20 mM 4-Br-benzene diazonium. Absorption changes recorded at 700 nm (right) at different concentration of 4-Br-benzene diazonium. The inset shows the observed rate at each concentration that was used to determine the rate constant for electron transfer. This rate constant was used, in concert with equations 2.1–2.3, to fit the absorption changes at 700 nm.
