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

The treatment of α-bromoarylacetonitriles with AgNO3 generates cyanohydrin nitrate intermediates, which easily eliminate nitrous acid with the formation of carbonyl bond to afford aroyl cyanides in good to high yields.

efficient enantioselectivehydrogenation of 1,2-dicyanoalkenes catalyzed by the complex of rhodium and f-spiroPhos has been developed. A series of 1,2-dicyanoalkenes were successfully hydrogenated to the corresponding chiral 1,2-dicyanoalkanes under mild conditions with excellent enantioselectivities (up to 98% ee). This methodology provides efficient access to the asymmetric synthesis of chiral diamines

efficient synthesis of α-amino-α-aryl carbonitriles through the three-component reaction of arynes, aroylcyanides, and DMF in a single step is described. DMF was not only used as the solvent, but it also participated in the reaction as a component. Used as the cyanide sources, the aroylcyanides solved the toxicity and solubility problems associated with the use of HCN or metal cyanides in the Strecker

Members of a novel class of organic nitriles related to an indole alkoaloid of Dithyrea wislizenii (Cruciferae) have been discovered to be potent feeding inhibitors of the fall armyworm and European corn borer.
