The described method provides an efficient cyanation reaction of thiophene halides using tris(dibenzylidene-acetone)dipalladium(0), 1,1′-bis-(diphenylphosphino)ferrocene) and zinc powder as the catalyst system and Zn(CN)2 as the cyanide source. Several thiophenes with various substituents are effectively cyanated under these conditions.
