An air‐stable, copper‐free and highly efficient Dppc + PF 6 − –PdCl 2 –[bmim][PF 6 ] catalytic system has been developed for the Sonogashira coupling reaction of aryl iodides with various aryl‐ and alkylacetylenes. The catalytic system allows for facile separation and can be recycled at least eight times with minimal loss of activity. Copyright © 2007 John Wiley & Sons, Ltd.
