Processes For Forming The Cyano Group Patents (Class 558/308)
  • Patent number: 5359119
    Abstract: A low temperature, solution phase process for synthesizing nitriles such as acrylonitrile and benzylnitrile is provided which makes use of a transition metal complex bearing an imido moiety to form a final nitrile corresponding to the moiety. In practice, a solution of a transition metal complex is formed in a non-interfering solvent, and the solution is reacted under time and temperature conditions to form the desired nitrile. The solution may also contain a base such as pyridine.
