Abstract: Azo dyestuff having the formula ##STR1## in which A is an aromatic carbocyclic radical containing a CN substituent in the o-position to the azo group and K is the radical of a coupling component as well as the process for their production are disclosed. The process involves cyano exchange between a metal cyanide, e.g. CuCN and the corresponding dyestuff containing Cl or Br instead of CN, in an organic solvent particularly polar aprotic organic solvents, e.g. dimethyl sulfoxide. The dyestuffs are suitable for dyeing a variety of fiber material such as cotton, wool, silk as well as synthetic materials such as polyamide and polyethylene terephthalate to give dyeings which are characterized by great clearness and good general fastness properties.
