A general catalyzed cyanation of hetero(aryl) chlorides using less toxic Zn(CN)2 as the cyanide source relies on the use of inexpensive NiCl26H2O/dppf/Zn as the catalytic system and DMAP as additive. The cyanation occurs under mild reaction conditions with wide functional group tolerance. The method was also successfully extended to aryl bromides and aryl iodides.
