Abstract
|
|
|
|
In Bucherer-Berg’’s reaction of alpha-piperidinoacetophenone with KCN and (NH4)2CO3 in dilute alcohol solution to form hydantoin, the expected 5-phenyl-5-piperidinomethylhydantoin was not formed. In this reaction alpha-piperidinomethyl group was eliminated and 5-phenylhydantoin was obtained. According to GC/MS study of the reaction mixture, the one of the chromatograms, which has mole peak 124, was identified as alpha-piperidinoacetonitrile. Under the pressurized condition, diphenylhydantil was obtained instead of 5-phenylhydantoin, which might have dimerized to the former.
