Abstract :
Commercially available, air- and water-stable naphthoquinone imidazolin-2-ylidene-palladium(0) complexes were found to be highly active one-component catalysts for the amination of aryl halides. With these very robust catalysts, the expensive bases Cs2CO3 or NaOt-Bu traditionally used can be replaced by KOH. A convenient reaction protocol has been developed for the coupling of a wide range of aryl chlorides with primary or secondary amines.
