Transition-metal-catalyzed regioselective aroyl- and trifluoro-acetylthiolation of alkynes using thioesters

Transition-metal-catalyzed regioselective aroyl- and trifluoro-acetylthiolation of alkynes using thioesters

Intermolecular CO-retained carbothiolation of alkynes using thioesters took place to afford beta-SR substituted enone derivatives; the choice of catalyst (Pd(dba)(2)-dppe) and the introduction of a CF(3) group into the thioesters are the key to achieving the transformation.
