The palladium-catalyzed Heck reaction of aryl halides in the presence of phosphite ligands is described for the first time. Aryl bromides and even electron deficient aryl chlorides can be coupled efficiently (turnover numbers up to 31 000) with different olefins using palladium/trialkyl- or triaryl phosphite mixtures as catalysts.
