The palladium- and copper-catalyzed coupling of iodonium salts with alk-1-ynes in the presence of atmospheric pressure of carbon monoxide in DME/H 2O (4:1) and Pd(OAc) 2 (0.2 mol%) [or Pd(OAc) 2 with CuI (10 mol%) and NaHCO 3 (1.2 equiv)], or CuI (10 mol%) and NaHCO 3 (2.2. equiv) at 30°C... mehr

Copper-catalyzed cross- and carbonylative coupling ­reactions have been achieved in the reaction of a variety of alkynyl­iodonium salts with arylboronic acids and organostannanes under the mild reaction conditions in high yield. Our investigation shows that the alkynylidonium tetrafluoroborates... mehr
