Worth its salt: The palladium‐catalyzed decarboxylativecoupling of the cyanoacetate salt as well as its mono‐ and disubstituted derivatives with aryl chlorides, bromides, and triflates is described (see scheme). This reaction is potentially useful for the preparation of a diverse array of α‐arylnitriles and has good functional group tolerance. S‐Phos=2‐(2,6‐dimethoxybiphenyl)dicyclohexylphosphine)
