  • Method for producing an &agr;-aminonitrile from a tertiary anime and a cyanide through oxidation with oxygen by using a transition metal catalyst
    Patent number: 6486340
    Abstract: A method for producing an &agr;-aminonitrile, is disclosed, which method includes the step of oxidizing a tertiary amine with oxygen by using a transition metal catalyst in the presence of a cyanide. The &agr;-aminonitrile thus obtained can be easily converted to amino acids as well as various nitrogen-containing physiologically active materials.
