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‐Bu4NI as supporting electrolyte and methanol as solvent and proton source. Deuterodechlorination of trichloroacetamide was also successful when methanol‐d4 was used as solvent under identical electrochemical conditions.
