Adsorption effects on the selective electrofuorination of
a-(phenylthio)acetamides and a-(phenylthio)acetates
in Et3N 3HF/CH3CN.

Abstract
Cyclic voltammetric behaviour of a-(phenylthio)acetamides and a-(phenylthio)acetates were compared in CH3CN/tetrabutylammonium
perchlorate (TBAP) and CH3CN/Et3N 3HF to assess the in¯uence of ¯uoride ion on the oxidative pathway. These studies support the
Pummerer mechanistic pathway involving an initial attack at sulfur in selective electro¯uorination (SEF). A linear correlation between the
peak current values in cyclic voltammetry and overall synthetic yield in preparative electrolysis was obtained suggesting the importance of
weak blocking or a reactive adsorption effect on the overall synthetic processes. Other factors in¯uencing the adsorption and insulation of
electrode surfaces during the SEF are also discussed.
