In 1904, Jocelyn Field Thorpe and co-workers conducted the first studies of the intermolecular dimerization of nitriles. A short time later, the first example of a dinitrile cyclization was described by Moore and Thorpe. Initially, all products of dinitrile cyclization reactions were characterized as imines. However, in 1955, it was determined that the product of the cyclization of adiponitrile was in actuality an enamine. The enamine structure for the product of dinitrile cyclizations has since been confirmed through numerous other studies, and makes sense chemically. The conjugated enamine would be expected to be more stable than the corresponding nonconjugated P-iminonitrile.
