Spectra of Azlactones. I. Azlactones Derived from Substituted Benzaldehydes and Hippuric and Nitrohippuric Acids

The absorption spectra of a series of azlactones obtained by condensation of hippuric acid, ο-, m- and p-nitrohippuric acids, with benzaldehyde and substituted benzaldehydes, have been determined in acetic acid solution up to 255 mµ. All the azlactones show a band of high intensity, each with a maxi...

Azlactones Derived from Substituted Benzaldehydes and Hippuric and Nitrohippuric Acids Bassi, Daniel Antonio Deulofeu, Venancio Ortega, Fernando A. F. The absorption spectra of a series of azlactones obtained by condensation of hippuric acid, ο-, m- and p-nitrohippuric acids, with benzaldehyde and substituted benzaldehydes, have been determined in acetic acid solution up to 255 mµ. All the azlactones show a band of high intensity, each with a maximum varying with substitution, at 346-430 mµ. In some azlactones, a second, less intense band, with a maximum at 256-310 mµ is found. It is absent in azlactones where a nitro group is placed ortho or meta, in phenyls R1 or R2 (Formula I). Some correlations, between the position of the first maximum in the absorption spectra and the substituents, are described. © 1953, American Chemical Society. All rights reserved. Fil:Bassi, D.A.
