transmetalation step. A highly efficient gold and palladium combined methodology for the Sonogashiracoupling of a wide array of electronically and structurally diverse aryl and heteroaryl halides is described. The orthogonal reactivity of the two metals shows high selectivity and extreme functional group tolerance in Sonogashiracoupling. A brief mechanistic study reveals that the gold acetylide intermediate enters
