A silver‐catalyzed decarboxylative trifluoromethylthiolation of secondary and tertiary carboxylic acids under mild conditions tolerates a wide range of functional groups. The reaction was dramatically accelerated by its performance in an aqueous emulsion, which was formed by the addition of sodium dodecyl sulfate to water. It was proposed that the radical, which was generated from the silver‐catalyzed...
Eine chirale Lewis‐Base oder ein Phasentransferkatalysator (PTC) können die hoch enantioselektive Trifluormethylthiolierung von β‐Ketoestern mit dem bereits bekannten SCF3‐Reagens vermitteln (siehe Schema). Reaktionen von Indanon‐abgeleiteten β‐Ketoestern verlaufen mit hohen Ausbeuten und exzellenten ee‐Werten mit Chinin als Katalysator. Reaktionen von Tetralon‐ oder 1‐Benzosuberon‐abgeleiteten β‐Ketoestern...
