Abstract Functionalized alkyl 2‐benzylacrylates and 2‐benzylacrylonitriles were synthesized by means of atom‐economic cross‐couplings of Baylis–Hillman bromides or acetates with BiAr 3 under palladium‐catalyzed conditions. These reactions, involving threefold aryl couplings using BiAr 3 reagents with bromides and acetates, are fast and are completed in 1–2 h with high product yields.
