[TEMPO] (blue) and [TEMPO+] (red) obtained by using CSCA at a rotating disk electrode upon mixing CH3CN solutions of TEMPO and Fe(NO3)3•9H2O in the absence (A) and presence (B) of 1-phenylethanol (50 mM). Conditions: 3 mM [TEMPO] and [Fe], 0.1 M NBu4PF6 in CH3CN; Ic and Ia measured at −0.16 and 0.64 V vs. Fc0/+, respectively, 1000 RPM.
