Abstract
Hydrazones IV, derived from substituted benzaldehydes and N-aminophthalimide, experience an exchange reaction with one equivalent of 2,4-dinitrophenylhydrazine under conditions free of added mineral acid to cleanly and irreversibly produce the related 2,4-dinitrophenylhydrazones V in good yields. Although literature melting points for compounds V may vary from one reference to another, the infrared spectra (v (mull), cm−1; IV: 1770, 1710; V: 3280, 1615, 1580, 1510) of starting materials and products in the exchange process are strikingly different and permit ready characterization.
