Sažetak
In the reaction of phenylhydrazine with n-benzylpenilloic acids
(Ia or Ila) n-penicillamine was obtained in high yield and purity.
The lack of reactivity of N-acyl derivatives (Ib or Ub) with phenylhydrazine
indicated that the above reaction proceeded through
the open chain imine tautomer of Ia or Ila (IV). The epim~risation
of n-benzylpenilloic acid (Ia and Ha) in aprotic solvents was studied
by using PMR spectroscopy.
