Feeling the pinch: Aryl bromides can be coupled with phenylboronic acid quantitatively within a few minutes by using pincer-type catalysts bearing aminophosphine substituents. [Pd(Cl)2P(NR2)3] has been used as a template for the pincer core directly on the metal center (see scheme, NR2=piperidinyl, X=NH or O), which makes the independent synthesis and purification of the air- and moisture-sensitive ligand systems unnecessary.
