a Cyclic voltammograms on a glassy carbon electrode (ϕ 3 mm) at 0.1 Vs−1 under nitrogen. Black line, 3-methyl N-acetyl indole (1a); red line, mercaptoethanol (2o); blue line, ethane-1,2-dithiol (2q). b EPR measurements of 2o in the presence of DMPO under constant current conditions for 6 min. c EPR measurements of 1a and 2o in the same conditions. d Radical cation trapping experiment by P(OEt)3. e Controlled potential electrolysis.
