Reactions in which Copper(I) cyanide is involved

  • 3CN^- + Cu^2+ -> (CN)2 + CuCN
  • 4{M}CN + 2Cu{X}2 -> (CN)2 + 2CuCN + 4{M}{X} , where M = Na K Li Rb Cs; X = F Cl Br I (NO3)
  • 2CuSO4 + 4{M}CN -> (CN)2 + 2CuCN + 2{M}2SO4 , where M = K Na Li Rb Cs
  • 2CuSO4 + NaHSO3 + H2O + 2NaCN → 2CuCN + 3NaHSO4
