Copper‐Catalyzed Decarboxylative Synthesis of α‐Ketothioamides Using α,β‐Unsaturated Arylcarboxylic Acids, Alicyclic Secondary Amines and Elemental Sulfur.

An efficient and straightforward synthesis of α‐ketothioamides has been accomplished via in situ decarboxylative oxidative thioamidation using α,β‐unsaturated arylcarboxylic acids, alicyclic secondary amines and elemental sulfur under solvent‐free aerobic conditions. [ABSTRACT FROM AUTHOR]
