Abstract
In the previous paper3), we reported a method of synthesizing nitriles from benzyl and alkyl amines by using nickel peroxide as an oxidant. In these reactions, the reaction was initiated by the hydrogen radical abstraction from the methylene and amino groups by nickel peroxide and produced the aldimine intermediate, which was further oxidized to a nitrile. Several papers have been reported describing one-step syntheses of nitriles from the corresponding aldehydes and ammonia in the liquid phase by the oxidation with several kinds of oxidants.
