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)

The palladium‐catalyzed decarboxylative benzylation of α‐cyano aliphatic carboxylatesalts with benzyl electrophiles was discovered. This reaction exhibits good functional group compatibility and proceeds under relatively mild conditions. A diverse range of quaternary, tertiary and secondary β‐aryl nitriles can be conveniently prepared by this method.
Cu-catalyzed decarboxylative alkynylation of quaternary a-cyano acetate salts with alkynyl bromides and alkynyl chlorides is described. This new reaction can be used for preparing functionalized butynenitrile derivatives.
