Hydrocyanation of α,ω-diynes without the use of HCN has been described.Cyanonickelate, prepared by reducing 2- with NaBH4 or Zn in the presence of excess KCN in water or ethylene glycol, catalyzes hydrocyanation of α,ω-diynes, HCC(CH2)nCCH to give quantitatively CH3CH(CN)(CH2)nCH(CN)CH3, a new series of acyclic dinitriles.Importance of the preliminary formation of a (?-acetylene)nickel(0) complex for the hydrocyanation has been suggested.
