Abstract
methylpiperidin-N-oxyl (TEMPO), are known to be an effective redox mediator for the oxidation of amines.1,2 We have reported that a graphite felt electrode coated with a thin poly(acrylic acid) layer immobilizing 4amino-TEMPO can be used for the electrocatalytic oxidation of amines.3 On the other hand, a self-assembled monolayer has attracted a great deal of interest because of its possible applications to many fields, such as biosensors and display devices.4,5 Many self-assembled monolayer-modified electrodes report on the monolayer-immobilization of thiols containing redox active functional groups on gold electrodes.6–10 Recently, Fuchigami et al.11 have prepared a self-assembled TEMPO-modified electrode for the electrocatalysis of 4-methylbenzyl alcohol. In this pepar, we report on the enantioselective voltammetric behavior of chiral amines at gold electrodes modified with a mixed monolayer of chiral nitroxyl radical compound and hexadecanethiol.
