The present invention is directed to compositions of specific carboxylic acid, fatty acid or oil derivatives containing nitrile groups and methods of their preparation. The preparation involves a hydrocyanation reaction. A method of hydrgenating the nitrile containing carboxylic acid acids obtained by above hydrocyanation to produce amine containing carbixylic acids is also disclosed in this invention.

The present invention is directed to compositions of specific carboxylic acid, fatty acid or oil derivatives containing nitrile groups and methods of their preparation. The preparation involves a hydrocyanation reaction. A method of hydrogenating the nitrile containing carboxylic acids obtained by the above hydrocyanation to produce amine containing carboxylic acids is also disclosed in this invention.
secondary, and tertiary alkyl nitriles and thiocyanates are easily synthesized. Moreover, an asymmetric decarboxylative cyanation by applying a chiralCu catalyst is also developed to afford chiral nitriles in high enantioselectivity. The mechanistic details and the origin of the high enantioselectivity are further investigated by the mechanistic experiments and the density functional theory calculations.
