Abstract

Palladium-catalyzed CN bond-forming reactions have evolved into a versatile and efficient synthetic transformation. 1 However, the lack of a general palladium-based catalyst for aryl chloride substitution reactions, 2, 3 as well as the elevated reaction temperatures often required, prompted us to search for new, more active ligands.
