Synthesis and characterization of 2,3,5,6-tetraphenylpyrazine-N, N-dioxide: New nitrone dimer species

The synthesis, characterization and physical properties of 2,3,5,6-tetraphenylpyrazine-N,N-dioxide presently are reported. A specific reduction mechanism of an oxime using zinc with NH4Cl to yield hydroxylamine was performed. This was followed by a condensation reaction with sulfuric acid that leads to 2,3,5,6-tetraphenylpyrazine-N,N-dioxide. The product was characterized by means of IR, UV,1H-NMR and13C-NMR spectroscopy which were complemented by theoretical computations. The Japan Institute of Heterocyclic Chemistry.
