Selective Hydro‐ and Deuterodechlorination of Trichloroacetamides under Controlled Electrochemical Conditions To Prepare Mono‐, Di‐, and Deuterochloroacetamides

Mono‐ and dichloro acetamides were prepared via a hydrodechlorination reaction of trichloroacetamides under controlled electrochemical conditions. The reactions were carried out in an undivided cell with constant current flow using n ‐Bu 4 NI as supporting electrolyte and methanol as solvent and proton source. Deuterodechlorination of trichloroacetamide was also successful when methanol‐ d 4 was used as solvent under identical electrochemical conditions.
