The research results were published in《Organic Letters》 in 2022.Safety of 3-Cyanopyridine The article conveys some information:

The cleavage and functionalization of C-C bonds has emerged as a powerful tool for discovery of new transformations. Herein, authors report a protocol that enables direct synthesis of nitriles via copper-catalyzed oxidative cleavage and cyanation of C-C bonds in a wide variety of multicarbon alkyl-substituted (hetero)arenes. Detailed mechanistic studies reveal that a tandem oxidative process is involved in this transformation. To complete the study, the researchers used 3-Cyanopyridine (cas: 100-54-9) .
