A novel and fast Sonogashira coupling reaction of terminal alkynes
with hypervalent iodonium salts was achieved in the presence of
catalytic amount of palladium chloride and silver(I) iodide,
providing a convenient method for the synthesis of arylalkynes
in good yields in a short time.
Sonogashira reaction - terminal alkynes - hypervalent iodonium
salts - Pd/Ag catalyst
