Four′s a crowd: An efficient protocol for the formation of benzylic quaternary centers via arylation of enones using a catalyst made from Pd(O 2 CCF 3 ) 2 and 2,2′‐bipyridine is developed. For cyclic substrates, catalyst loadings as low as 1 mol % Pd are enough to afford excellent yields (>90 %) using a variety of arylboronic acids. In case of acyclic substrates, the addition of KSbF 6 was found to improve conversions and yields.
