Electrochemically initiated 1,4 additions: a versatile route to the determination of thiols

Abstract:

The electrochemical generation of quinoid intermediates and their subsequent reaction with sulphydryl thiols (RSH) have been investigated as a method by which the latter can be quantified. Nucleophilic addition of the thiol species to the electrogenerated quinoid structure leads to the production of a chemically reduced adduct whose subsequent re-oxidation at the electrode leads to an amplification of the oxidative current. This can be correlated to the concentration of thiol present within t...
