palladium‐catalyzed β‐arylation of ester enolates with arylbromides was studied both experimentally and computationally. First, the effect of the ligand on the selectivity of the α/β‐arylation reactions of ortho‐ and meta‐fluorobromobenzene was described. Selective β‐arylation was observed for the reaction of o‐fluorobromobenzene with a range of biarylphosphine ligands, whereas α‐arylation was predominantly

Published as part of the Special Section dedicated to Scott E. Denmark on the occasion of his 65th birthday Abstract A procedure for the α-arylation of α,α-disubstituted esters and ketones to generate quaternary carbon centers is described. The developed protocol is operationally simple and employs an air- and moisture-stable dinuclear Pd(I) complex [Pd(μ-I)(Pt-Bu3)]2 to mediate selective α-arylation
