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)

A new and practical α‐monomethylation strategy using an amine‐borane/N,N‐dimethylformamide (R3N‐BH3/DMF) system as the methyl source was developed. This protocol has been found to be effective in the α‐monomethylation of arylacetonitriles and arylacetamides. Mechanistic studies revealed that the formyl group of DMF delivered the carbon and one hydrogen atoms of the methyl group, and R3N‐BH3 donated

nickel-catalyzed demethylative cyanation and decarboxylative cyanomethylation of arylhalides are described here. Commercially available bromoacetonitrile was found to act as an efficient cyanating reagent for the photoinduced cyanation reaction in the absence of a photocatalyst. Moreover, photoredox and nickel dual-catalyzed decarboxylative cyanomethylation of arylhalides has also been realized using
