    Interconversion of the Tautomers of 2-Benzylidene-4-Methyl-3-Oxo-Pentanoic Acid Phenylamide During Gas Chromatography

    Tautomerization of 2-benzylidene-4-methyl-3-oxo-pentanoic acid phenylamide has been studied by NMR and GC-MS. The two tautomers were separated on an HP-5 column, which enabled the kinetic and the thermodynamic...
