Nickel-Catalyzed C–CN Bond Formation via Decarbonylative Cyanation of Esters, Amides, and Intramolecular Recombination Fragment Coupling of Acyl Cyanides
An efficientnickel-catalyzed decarbonylative cyanation reaction which allows the direct functional-group interconversion of readily available esters into the corresponding nitriles was developed. This reaction successfully offers access to structurally diverse nitriles with high efficiency and excellent functional-group tolerance and provides a good alternative to classical synthetic pathways from
Phosphine organocatalysis enabled vicinal acylcyanation of alkynoates with acyl cyanides to form acrylonitrile derivatives with a tetrasubstituted alkene moiety. The acyl and cyano groups were introduced at the α and β carbon atoms, respectively, of the C–C triple bond in the alkynoates with complete regioselectivity and high anti stereoselectivity. A variety of functional groups in the acyl cyanides

A practical cyanation of aroyl chlorides with 0.2 equivalent of non-toxic cyanide source, K 4 [Fe(CN) 6 ], 3 mol% AgI, 4 mol% PEG-400, and 3 mol% KI as the catalyst system is described. The reactions were performed in DMF at room temperature and provided the corresponding aroylcyanides in 64-89% yield, typically in less than ten hours.

Cu-catalyzed domino decyanation and cyanation reaction of acyl cyanides with amines or alcohols have been developed. The cyanosources were generated in situ via C–CN cleavage yielding the corresponding cyano substituted amides or esters in moderate to excellent yields. This approach features a cheap copper catalyst, domino decyanation and cyanation reaction, readily available starting materials, broad
