The reactivity of electrochemically generated radical cations toward alcohol and p-toluene sulfonamide nucleophiles was directly investigated through competition experiments. Alcohol-trapping of the radical cation is the kinetically favored pathway and is

A competition experiment was designed so that the relative rates of anodic cyclization reactions under various electrolysis conditions can be determined. Reactions with ketene dithioacetal and enol ether-based substrates that use lithium methoxide as a base were shown to proceed through radical cation intermediates that were trapped by a sulfonamide anion. Results for the oxidative coupling of a vinyl sulfide with a sulfonamide anion using the same conditions were consistent with the reaction proceeding through a nitrogen-radical.
