In some cases, the catalyzed mechanism may include additional steps.In a article, 34846-65-6, molcular formula is C10H6N2, introducing its new discovery.

An improved copper catalyst system for the cyanation of heteroaryl halides leading to substituted heteroaryl nitriles is described. The catalyst system consists of simple CuI and N-alkylimidazoles, and mimics known Cu-containing metalloproteins. It is stable, commercially available, cheap and easily tunable. By using inexpensive and non-toxic K4[Fe(CN)6] and the novel Cu catalysts we were able to cyanate both activated and non-activated heteroarenes with high yield and selectivity. The generality of the procedure is demonstrated by a variety of different examples, some of which did not react under other known methods. Georg Thieme Verlag Stuttgart.

Homogeneous conditions for the palladium-catalyzed cyanation of aryl halides were developed. This new system features a broad scope of aryl chlorides and bromides, uses 2-propanol or 1-butanol as solvent, and is readily scalable. The same conditions can also provide simple benzonitriles using the recently developed (TMEDA)NiCl(o-tolyl) precatalyst in conjunction with 1,1?-bis(diphenylphosphino)ferrocene (dppf) as a ligand.

The cyanation of arylboronic acids by using acetonitrile as the “CN” source has been achieved under a Cu(cat.)/TEMPO system (TEMPO=2,2,6,6-tetramethylpiperidine N-oxide). The broad substrate scope includes a variety of electron-rich and electron-poor arylboronic acids, which react well to give the cyanated products in high to excellent yields. Mechanistic studies reveal that TEMPO-CH2CN, generated in situ, is an active cyanating reagent, and shows high reactivity for the formation of the CN- moiety. Moreover, TEMPO acts as a cheap oxidant to enable the reaction to be catalytic in copper.
