Phno chemistry
WebbA technique for preparing and handling stable solutions of the nitrobenzene radical-anion, (PhNo 2 ·) –, in dry methyl cyanide is described. The first-order decay of this radical in the presence of a small percentage of an aqueous buffer is ascribed to the diffusion-controlled rate of neutralisation of the anion. Webb1 juni 2016 · An electrochemically generated redox couple (PhNHOH/PhNO) exhibits reversible voltammetric response at ∼−0.06 V with a surface coverage of (7.19 ± 0.26) × 10 −9 mol cm −2. The redox couple efficiently mediates the oxidation of NADH at 0.04 V, which is ∼600 mV less positive potential than the unmodified electrode.
