norbornene-mediated tandem amination/cyanation reaction via Catellani-type C–H functionalization was developed using N-benzoyloxyamines as the amination reagent and Zn(CN)2 as the terminating agent. This transformation, in which one C–N bond and one C–C bond are formed, provides an efficient approach for the synthesis of ortho-aminated benzonitriles in one pot from easily accessible starting materials

Efficient tandem ortho-C–H-amination/ipso-cyanation of iodoarenes was accomplished under a norbornene-mediated Pd-catalyzed process. A series of functionalized 2-aminobenzonitriles with much potential in the pharmaceutical industry were obtained by this protocol. This strategy was successfully employed for substitution with two cyano and four amino functionalities in an arene unit in one step under
